A simulation of fuzzy control algorithm based on the IMC-PID controller

摘要

This paper studies a fuzzy algorithm control system based on internal model control theory. The main steam temperature object of coal-fired boiler power plants is large inertia, large delay and time varying. The IMC-PID controller cannot obtain satisfactory control effect. The control system added a fuzzy control algorithm can adjust the proportionality coefficient of the IMC-PID controller online. ]Thus, in the main steam temperature control system the IMC-PID controller's control effects is improved. Simulation result verifies this conclusion.
