Application of improved PID dynamic matrix control algorithm in EPA

Based on the analysis of PID control algorithm and dynamic matrix control (DMC) algorithm, the derivation of proportional integral derivative dynamic matrix control (PIDDMC) algorithm is given. Combined the virtues of the two algorithms, this kind of algorithm is of the advantages of PID algorithm, which is simple in structure, reliable in operation and robust in performance, and of predictive function. The influence of PIDDMC controller parameter tuning on system performance is investigated in time domain. The parameter election range is researched. Compared simulation results in a real time Ethernet for Plant Automation (EPA) experiment device, PIDDMC algorithm has better performance than conventional DMC algorithm to make the system have satisfactory stability and transition characteristics, and grounds well for engineering application.
