摘　　要：首先给出对象不确定性描述,基于阶跃响应模型提出单值预测函数控制和双值预测函数控制两类算法的设计．然后将系统控制结构归结为内模控制结构,利用多项式Jury主系数定理,分别给出基于两类预测函数控制算法设计的闭环控制系统鲁棒稳定的充分条件．最后通过仿真实验讨论了控制器的参数调节．The uncertainty description of the controlled processes is firstly given. A single value predictive functional control algorithm and a double value predictive functional control algorithm are then proposed for stable processes on the basis of the step response model. Furthermore, the performance analysis of the closed-loop control system is discussed in the frame of the internal model structure, and the robust stability conditions of the resulted closed-loop control system are given based on Jury＇s dominant coefficient criterion. Finally, the discussion for the parameters tuning is presented in the simulations.
