Based on the model of coordinated control object, this paper firstly eliminates the strong coupling between the input and output variables using feedforward compensation decoupling method. The fuzzy adaptive PID controller, using the decoupled model, is designed and optimized for the main steam pressure channel and the intermediate point temperature channel of the coordinated control object. The simulation results show that, using the fuzzy adaptive PID controller optimized by quantum-behaved particle swarm optimization algorithm, the overshoot of controlled variable decreases and the adjustment time reduces in response to a step change. Furthermore, the control performance of PID controller is greatly improved.
