Problems solved by technology

Among them, the servo amplification part that controls the electric actuator is usually composed of an input isolation amplifier circuit, a comparison, a trigger circuit, and a power output circuit. The input is generally isolated by a coil, and then amplified by a magnetic amplifier; The voltage comparator composed of the trigger circuit adopts the relaxation oscillation trigger circuit, its stability and reliability are poor; the power output circuit is a thyristor output circuit, and the servo motor speed is fixed, which is difficult to adjust
This type of electric actuator cannot obtain some characteristic parameters of itself during the control process, so that the control accuracy and reliability are not high, and usually only single-channel analog sampling can be performed, and only one input signal can be collected, such as current Or resistance, and then compare the detection signal with the input signal, and then send the control signal to the drive circuit to control the displacement output of the actuator; although some electric actuators are equipped with an alarm circuit, no chain protection measures are adopted. In the alarm state, there is still insecurity, so the electric actuator controlled by this kind of servo amplifier cannot be applied in some occasions that require high precision, reliability and stability.

Abstract

The present invention belongs to the field of automatic control technology, and is especially one kind of adaptive intelligent controller for electric executing mechanism and its adaptive control method. The controller includes servo amplifying part and electric executing mechanism part, and features that the servo amplifying part consists of microprocessor, multiplexer circuit, A / D converter, photoelectric isolator circuit, output driver circuit, solid relay and linkage protecting circuit. The adaptive control method includes the steps of self-learning characteristic parameters of electric executing mechanism and adaptive intelligent control. Owing to the increased adapting function of the servo amplifier, various characteristic parameters of the electric executing mechanism may be obtained during switching from manual control to automatic control, and this avoids overshoot and raises stability, safety and reliability of the controller.
