Abstract
본 발명은 피드백시스템의 히스테리시스 동작특성을 개선함으로써 동작량의 오차를 보정하여 대상물을 보다 정확히 제어할 수 있도록 하는 피드백시스템의 히스테리시스 동작특성 제어방법에 관한 것이다.The present invention relates to a hysteresis operation characteristic control method of a feedback system which improves a hysteresis operation characteristic of a feedback system and thereby corrects an error of an operation amount to more accurately control an object.
본 발명은 센서(10)의 기준신호(A)에 의해 제어부(20)에서 제어량(B)을 산출한 후, 상기 제어량(B)만큼 액츄에이터(30)를 구동하여 대상물(40)을 동작시키고, 상기 액츄에이터(30)의 구동량(C)을 상기 센서(10)의 기준신호(A)에 감산함으로써 제어부(20)의 제어량(B)을 재산출하여 상기 액츄에이터(30)의 구동량(C)을 보정하도록 하는 피드백시스템에 있어서, 상기 제어부(20)의 입출력신호가 갖는 히스테리시스 특성곡선(21,22)을 사각의 가상선(23,24)으로 모델링한 후, 상기 사각의 가상선(23,24)에 대해 반전된 히스테리시스 특성곡선(25,26)을 갖는 신호를 인버스회로(50)를 통해 출력하여 상기 제어부(20)의 출력신호에 가산하도록 한 것이다.The present invention is characterized in that the control unit 20 calculates the control amount B by the reference signal A of the sensor 10 and then drives the actuator 30 by the control amount B to operate the object 40, The control amount B of the control unit 20 is re-calculated by subtracting the drive amount C of the actuator 30 from the reference signal A of the sensor 10 to calculate the drive amount C of the actuator 30, The hysteresis characteristic curves 21 and 22 of the input and output signals of the control unit 20 are modeled by rectangular imaginary lines 23 and 24 and then the imaginary lines 23, 24 by inverting the hysteresis characteristic curves 25, 26 through the inverse circuit 50 and adding them to the output signal of the control unit 20.
