Abstract :
The paper mainly expatiates on control theories, parameters, and transfer functions of electronic expansion valve system. It realizes optimal PD controller based on genetic algorithm acceptable for unstable object, with more conspicuous effect, and can be put to use in flux process control with high precision. The paper, in the meantime, illustrates the hardware connections and driving process of the stepper motor.
