摘要: 针对多包描述的时变不确定系统, 通过分析该方法的可行性和闭环稳定性, 提出一种变时域鲁棒预测控制器的设计方法, 使得在与现有方法有相同初始可行域的前提下, 保证了只要问题初始可行就有闭环系统二次稳定. 仿真结果表明了算法的有效性.

Abstract: By analyzing the feasibility and stability of systems with polytopic description, we proposed a variable horizon robust model predictive control algorithm. Retaining the same feasible set of initial conditions with the existing algorithm, our algorithm guarantees the robust stability of the closedloop system once the problem is initially feasible. The effectiveness of this algorithm is illustrated by a simulation example.

Key words: polytopic description, predictive control, feasibility, stability
