| 摘 要： | 提出一种改进的滚动时域控制算法来解决离散线性时不变系统的零和问题.与普通滚动时域控制不同的是,每一步中性能指标的终端权值矩阵将随着运算的进行不断更新,这等价于延长了时域长度.严格证明了该算法得到的控制律将收敛到无限零和问题的解,同时保证了闭环系统的一致最终指数稳定性,而不需要对终端状态、时域长度及终端性能指标施加额外的约束.最后仿真例子说明了该算法的有效性.

| Abstract: | The zero-sum games of discrete linear time-invariant(LTI) systems using a modified receding horizon control scheme were investigated.Different from conventional RHC,the proposed scheme updates its terminal weighting matrix in performance index as the stage moves forward.This is equivalent to lengthening the horizon size.The control policies generated by the proposed algorithm converge to the solution of the infinite horizon zero-sum games.Furthermore,it ensures the uniform ultimate exponential stability of closed-loop system without imposing any constraints on the terminal state,the horizon size,or the terminal cost.Simulation shows the effectiveness of the proposed algorithm. |
