Parameters Optimization of GPC Based on Swarm Algorithm

In this paper, the zeros of plant are decomposed into non-minimum phase zeros and minimum phase zeros; a new predictive equation is built. Combining generalized predictive control function with PID structure, and then optimizing the parameters of PID cost function based on swarm algorithm, thereby a new predictive algorithm is gained on the basis of introducing a restraining overshoot predictive method and model error amendment. Simulation results show this algorithm improves the controlling performance greatly, increases instantaneous respond.
