Research on application of ZigBee technology in PID controller parameter tuning

In view of problem of traditional PID parameter tuning such as installation and wiring of cable are quite cumbersome,operation lacks flexibility, the paper proposed to apply ZigBee technology to PID parameter tuning. Communication between PID parameter tuning controller host and field test equipment is achieved through ZigBee wireless networking method, so as to achieve the purposes of making PID parameter tuning device miniaturization, networking and intelligent. Simulation results show that the ZigBee technology can effectively reduce workload of parameter tuning experiment and improve flexibility and control quality of the PID controller, and extend its scope of application.
