Abstract
The paper mainly expatiates on control theories, parameters, and transfer functions for electronic expansion valve system. It realizes optimal fuzzy PD controller 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 connection, control theory, driving flow chart of stepper motor, and flow chart of the optimal fuzzy control process.
