摘　　要：通过分析被控过程产生反向响应的内在机理,基于过程阶跃响应系数利用预测函数控制算法实现反向响应过程的控制。将系统控制结构归结为内模控制结构,并在此基础上给出控制系统的鲁棒稳定性证明。该方法的优点是所得控制器结构简单、参数易于调节,且所给方法也适用于其他非最小相位系统的控制。实验结果证实该方法有很强的抗干扰能力和较好鲁棒性。After analyzing the characteristics of inverse response process, the step response model is used to serve as the internal model ,then predictive functional control algorithm is proposed for inverse response process. Moreover, the performance of the closed-loop control system is discussed on basis of internal model control structure. The advantages of the presented method are that the structure of the proposed controller is simple ,and the parameters are easy to tune. It is shown that the given approach can also be used to control stable processes with large time delay. Examples are given to illustrate that the proposed method can provide better closed-loop performance and better robustness.
