Design and Application of Self-Adaptive Controller Based on Q Series PLC

The control of simulated beer production line is implemented based on a Q series PLC controller of Mitsubishi company. The mathematical modeling method and the self-adaptive control strategy are introduced. The Mitsubishi PX-Developer software is adopted to design, run and debug online the PID and self-adaptive PID controller. Performance comparison between the two kinds of control strategy is made. It is shown that the self-adaptive PID control algorithm has the superiority.
