摘要
基于已有的一种稳定广义预测控制(SGPC)结构,以参考信号为优化变量对目标函数进行寻优,求出了控制器的滚动最优控制律,该控制律可以无静差地跟踪常数设定值.文中给出并证明了SGPC闭环控制系统的稳定性充分条件.数值仿真表明,该SGPC控制器可以保证闭环系统无稳态误差,并且适用于具有近似相消零极点的被控对象.
A receding horizon optimal control law is proposed in this paper based on a given stable generalized predictive controller （SGPC） configuration. Obtained by optimizing the objective function over the future reference signals, this control law can track with zero offset the constant set point. The sufficient condition is also given to ensure the closed-loop stability. Finally, numerical simulations are performed to show that the presented SGPC gnarantees the closed-loop system to be free from steady-state error and is applicable to the plant with zeros and poles which can be nearly cancelled.
