摘要
针对ＳＩＳＯ 线性离散系统，利用线性规划方法设计具有指定最优动态性能的鲁棒稳定控制器。当线性离散模型的零、极点已知时，将最优动态性能指标在指定输入信号下直接转化为线性规划问题，从而解出最优响应输出序列。最优动态性能指标与鲁棒稳定性的统一使该控制器的设计方法具备了工业应用条件。
Using linear programming, an approach of designing a robust stabiling controller which enjoys specific optimal dynamic performance indexes simultaneously is developed for SISO linear discrete-time systems. When the zeros and poles of a linear discrete-time system are known previously, the optimal dynamic performances for a given input signal are converted to a linear programming problem directly and the optimal output sequece is obtained by its solution. Also, the unity of optimal dynamic performances and the robust stability makes it possible that this design method is suitable for real-life application. The correctness of conclusions is verified by a simulation example.
