Abstract

PURPOSE:To enable to reliably operate an actuator even if a supply voltage decreases by varying a drive speed proportionally to the variation of the supply voltage. CONSTITUTION:When a supply voltage decreases, the drive frequency of an actuator is delayed. In other words, since this decreases the drive frequency, the pulse width becomes long, and one state naturally becomes long. Accordingly, since the drive current 1 reaches the set current value during one state as shown, the actuator reliably operates the drive torque without insufficiency. Particularly, this controlling method is adapted for controlling the actuator required for effective operation even if the drive speed is not to strict such as a stepping motor of an EGR valve or a waist gate of an automobile.

Stepping morphs, etc. that drive valves and wastegates, have a very strict driving speed and are required to operate reliably. There is a drawback that when the voltage decreases, it is easy to malfunction and become incapable of excitation. This point will be explained in detail. For example, if the motor is a 4-phase stepping motor φ7 high, A+++t+chi, - is one cycle (two-phase excitation), I

If the inductance of the motor is 3.6 mH, the winding resistance is 3.6Ω, and the series resistance is 7.20, then
The time constant at this time is 33 m sail. This also corresponds to the state A and the ξ sis width A, and if we consider this as the time at 1 to reach a certain current (saturation current), the deviation becomes a very large value when the supply voltage decreases. . Also, constant current,

When considering the time it takes to reach the current value, the time constant of inductance cannot be ignored. For example, as shown in FIG. 2, if the drive current does not reach the set current value during one state, the motor may malfunction or become inoperable due to insufficient drive torque.

(A method for controlling an actuator that can actually operate is described below based on an example. For example, when the supply voltage decreases, the driving speed of the actuator is slowed down. In other words, this reduces the driving frequency. Therefore, ξsis IJ becomes longer,
Naturally, one state is also longer. Therefore, as shown in FIG. 3, since the drive current reaches the set current value during one state, the actuator can operate reliably without running out of drive torque.

Although the drive speed does not have to be very strict, it is suitable for controlling actuators that require reliable operation.
