In particular, the present invention relates to a control device suitable for use in controlling the evaporator temperature of a refrigeration cycle by controlling the capacity of the compressor in a refrigeration cycle having a variable capacity compressor by an external control signal.

本出願人は先に特許文献１において、、とくに車両用空調装置におけるオートエアコンシステムに適用できる制御装置であり、制御対象出力がその目標値に到達するための過渡状態における目標応答を算出し指定する制御対象出力目標応答算出手段、制御対象出力目標応答値となるようなフィードフォワード制御入力予測手段を有し、かつ、制御対象出力目標応答と制御対象出力との偏差を演算する制御対象出力フィードバック手段を備えた制御装置であって、フィードフォワード制御入力とフィードバック制御入力との和を制御対象への制御入力として制御対象を制御するようにした制御装置を提案している。   The applicant of the present invention previously described in Patent Document 1 is a control device that can be applied to an auto air conditioner system particularly in a vehicle air conditioner, and calculates and designates a target response in a transient state for the control target output to reach its target value.

ところが、上記提案に係る制御装置においては、以下のような懸念点が残されている。すなわち、制御対象の出力が、上昇あるいは下降する場合において、極端に応答性が変わるとき、上記提案における制御対象出力応答目標値が一つの応答性しか持たない場合には、オーバーシュートの発生や、応答が遅くなることがある。また、制御対象の出力応答を、出力目標値の上昇あるいは下降においてそれぞれ異なるものとしたい場合には、上記先の提案に係る制御装置では対応できないことが考えられる。   However, the following concerns remain in the control device according to the above proposal. That is, when the output of the controlled object rises or falls, when the responsiveness changes extremely, if the controlled object output response target value in the above proposal has only one responsiveness, the occurrence of overshoot, Response may be slow. Further, when it is desired to make the output response of the controlled object different when the output target value increases or decreases, it is conceivable that the control device according to the above proposal cannot cope.

そこで本発明の課題は、上記先の提案に係る制御装置と同様に制御系としては簡素に構成しつつ、制御対象出力応答目標算出手段において、制御対象の応答性を、出力目標値の上昇または下降時に対応させてそれぞれ任意に変化させ、制御対象出力のより最適な応答が得られるようにした制御系を構築することにある。   Accordingly, an object of the present invention is to provide a control target output response target calculation unit that increases the output target value responsiveness in the control target output response target calculation means while simply configuring the control system in the same manner as the control device according to the above proposal. The purpose is to construct a control system in which a more optimal response of the control target output is obtained by arbitrarily changing each corresponding to the descending time.

上記課題を解決するために、本発明に係る制御装置は、制御対象を制御入力に基づき操作し、制御対象の出力としての制御量を制御する制御対象制御手段と、制御対象の出力を検知する制御対象出力検知手段と、制御対象出力値の目標値を設定する制御対象出力目標値設定手段と、制御対象への制御入力を演算する制御入力演算手段と、制御対象出力値が目標値に到達するための過渡状態における目標応答を算出し指定する制御対象出力目標応答算出手段と、制御対象出力目標応答値と制御対象出力値との偏差を参照することによりフィードバック制御入力を演算する制御対象出力フィードバック演算手段と、制御対象出力目標応答算出手段により演算される目標応答における過渡特性を実現するに必要なフィードフォワード制御入力を予測演算するフィードフォワード制御入力予測演算手段とを有する制御装置において、

Control target output detection means, control target output target value setting means for setting the target value of the control target output value, control input calculation means for calculating the control input to the control target, and the control target output value reaches the target value Control target output target response calculating means for calculating and specifying a target response in a transient state for controlling, and a control target output for calculating a feedback control input by referring to a deviation between the control target output target response value and the control target output value Predict feed-forward control input necessary to realize the transient characteristics in the target response calculated by the feedback calculation means and the control target output target response calculation means In the control device having a feed-forward control input prediction calculation means for calculation,
When the output target value is changed by the control target output target value setting means, the output target value before the change and the output target value after the change are compared, and when the output target value is increased or decreased, In each case, the calculation method of the output target response value in the control target output target response calculating means is changed, and the transient response of the control target output target is different when the output target value increases or decreases. Consists of features.

この制御装置においては、前記フィードフォワード制御入力予測演算手段としては、前記制御対象出力目標値設定手段により出力目標値が変更されたとき、出力目標値の上昇あるいは下降時においてそれぞれ、変更された制御対象出力目標の過渡応答を実現するのに必要なフィードフォワード制御入力予測演算方法を変更するようにすることができる。   In this control apparatus, the feedforward control input prediction calculation means includes a control that is changed when the output target value is raised or lowered when the output target value is changed by the control target output target value setting means. It is possible to change the feedforward control input prediction calculation method necessary for realizing the transient response of the target output target.

本発明に係る制御装置は、とくに車両用空調装置等における冷凍サイクルの制御に適用して好適なものである。本発明に係る冷凍サイクル制御装置は、外部からの制御信号により容量を可変可能な外部可変容量圧縮機と、高温高圧の冷媒を凝縮する凝縮器と、冷却器として室内に吹出す空気を冷却する蒸発器を備えた冷凍サイクルであって、蒸発器に空気を送風する送風機、蒸発器の目標温度を設定する蒸発器目標温度設定手段、蒸発器出口空気温度または蒸発器温度を検知する蒸発器温度検知手段、蒸発器温度を制御する蒸発器温度制御手段、蒸発器出口空気温度または蒸発器温度が蒸発器目標温度に到達するための過渡状態における目標応答を算出し指定する蒸発器温度目標応答算出手段、蒸発器温度目標応答値と蒸発器出口空気温度または蒸発器温度との偏差を参照することによりフィードバック制御入力を演算する蒸発器温度フィードバック制御入力演算手段、蒸発器温度目標応答算出手段により、算出される目標応答における過渡特性を実現するに必要なフィードフォワード制御入力を予測演算する蒸発器温度フィードフォワード制御入力予測演算手段を有する冷凍サイクルの制御装置において、
前記蒸発器目標温度設定手段により蒸発器温度目標値が変更されたとき、変更前の目標値と変更後の目標値を比較して、目標値を高くするとき、あるいは、低くするとき、それぞれの場合において、前記蒸発器温度目標応答算出手段により、異なる過渡応答となるような蒸発器目標応答値を算出することを可能にする目標応答性指定手段を有しており、該手段を介して、目標値の上昇あるいは下降時において、設定された目標値へ到達するまでの過渡応答をそれぞれ異なるものとすることを特徴とするものからなる。 The control device according to the present invention is particularly suitable for application to control of a refrigeration cycle in a vehicle air conditioner or the like. The refrigeration cycle control device according to the present invention cools an external variable capacity compressor whose capacity can be changed by an external control signal, a condenser that condenses high-temperature and high-pressure refrigerant, and air that is blown out indoors as a cooler. A refrigeration cycle equipped with an evaporator, which blows air to the evaporator, evaporator target temperature setting means for setting a target temperature of the evaporator, evaporator outlet air temperature or evaporator temperature for detecting the evaporator temperature Detecting means, evaporator temperature control means for controlling the evaporator temperature, evaporator temperature target response calculation for calculating and specifying the target response in the transient state for the evaporator outlet air temperature or the evaporator temperature to reach the evaporator target temperature Means, the evaporator temperature feedback control which calculates the feedback control input by referring to the deviation between the evaporator temperature target response value and the evaporator outlet air temperature or the evaporator temperature. An refrigeration cycle having an evaporator temperature feedforward control input prediction calculation means for predicting and calculating a feedforward control input necessary for realizing a transient characteristic in the calculated target response by an input calculation means and an evaporator temperature target response calculation means. In the control device,
When the evaporator temperature target value is changed by the evaporator target temperature setting means, the target value before the change is compared with the target value after the change, and the target value is increased or decreased. In this case, the evaporator temperature target response calculating means has target responsiveness specifying means that makes it possible to calculate an evaporator target response value that results in a different transient response. When the target value increases or decreases, the transient response until reaching the set target value is made different.

この冷凍サイクル制御装置においては、前記蒸発器温度フィードフォワード制御入力予測演算手段としては、前記蒸発器目標温度設定手段により蒸発器温度目標値が変更されたとき、目標値の上昇あるいは下降時においてそれぞれ、変更された制御温度目標の過渡応答を実現するのに必要なフィードフォワード制御入力予測演算方法を変更するようにすることができる。   In this refrigeration cycle control device, the evaporator temperature feedforward control input prediction calculation means is configured such that when the evaporator temperature target value is changed by the evaporator target temperature setting means, when the target value increases or decreases, The feedforward control input prediction calculation method required to realize the transient response of the changed control temperature target can be changed.

また、前記目標応答性指定手段が、前記蒸発器温度目標応答算出手段に用いる所定の応答性指定値群における応答性指定値を変更する手段からなり、冷凍サイクル熱負荷に応じて該応答性指定値を変更するようにすることができる。   The target responsiveness specifying means comprises means for changing a responsiveness specified value in a predetermined responsiveness specified value group used for the evaporator temperature target response calculating means, and the responsiveness specification according to a refrigeration cycle heat load. The value can be changed.

上記冷凍サイクル熱負荷としては、たとえば、外気温度に相関のある物理量、蒸発器への送風量に相関のある物理量、車両の速度に相関のある物理量、車両原動機の回転数に相関のある物理量のすべて、または少なくとも一つを検知したものを使用できる。   Examples of the refrigeration cycle heat load include physical quantities correlated to the outside air temperature, physical quantities correlated to the air flow to the evaporator, physical quantities correlated to the vehicle speed, and physical quantities correlated to the rotational speed of the vehicle prime mover. All or at least one detected can be used.

また、前記蒸発器温度制御手段は、外部からの制御信号により外部可変容量圧縮機の容量制御を行うことにより、蒸発器出口空気温度または蒸発器温度を制御するように構成することができる。   Further, the evaporator temperature control means can be configured to control the evaporator outlet air temperature or the evaporator temperature by controlling the capacity of the external variable capacity compressor by an external control signal.

本発明に係る制御装置によれば、制御対象出力の目標値が大きく、あるいは小さくなるように変更され、制御対象出力が上昇あるいは下降される場合にも、それぞれ任意の応答性を持つことで、所望の最適な応答性にて目標値への制御が可能となる。したがって、簡素で安価な制御系でありながら、オーバーシュートや応答遅れなどのない、望ましい制御を実現できる。   According to the control device according to the present invention, even when the target value of the control target output is changed so as to be large or small, and the control target output is increased or decreased, each has an arbitrary response. Control to the target value is possible with the desired optimum response. Therefore, it is possible to realize desirable control without overshoot or response delay while being a simple and inexpensive control system.
