【Abstract】 Based on lot of simulation experiments and theory analyses, research on selecting the optimization object function and the optimization strategy has been made in detail.The limitation of optimization parameter based on the object function with error and directly selecting damping factor has been showed. Though the simplex method is used to optimize the controller parameter for thermoprocess control systems, it will bring a natural default into existence. In the practical activities, this paper gives the possibility and the practicability of optimized parameters with expert system.更多还原
