| Abstract: | This paper presents the PID control theories, parameters, and transfer functions of electronic expansion valve system. To realize optimized control, a PID parameter setting way is put forward and an ideal PD controller is obtained. An empirical formula of PD controller for general situations is determined based on the experiments. With the PD parameters and the S7-200 PLC, the PD feedback control of the electronic expansion valve system is achieved with the help of integrated impulse-trigger stepping motor. |
