| 中文摘要 |
| 基于H∞控制理论以及切换系统稳定性理论, 对于多输入多输出(MIMO)多模型切换控制系统, 提出了一种可以有效抑制抖动和改善瞬态响应性能的鲁棒镇定控制器设计方法. 通过引入PI控制思想, 根据模型跟踪方法设计了增广状态反馈控制器, 并将控制器设计问题转化为方便求解的线性矩阵不等式(LMI). 该方法的最大优点是可以很方便的保证多模型切换系统的全局稳定性, 同时使得设计的控制器具有较强的鲁棒性. 将本文提出的方法应用到某型BTT导弹自动驾驶仪设计中, 仿真结果证明了此方法的有效性和优越性. |
| 英文摘要 |
| Based on the H-infinity control theory and the stability theory of switching system, this paper proposes a robust controller design method for a MIMO multi-model switching system to improve the transient performance and reduce the chattering during switching. An augmented state-feedback controller with PI control and model tracking is developed by solving several LMIs. This method is simple and feasible in designing the multi-model switching system for achieving global stability as well as robustness of the closed-loop system. It has been applied to the design of a BTT (bank-to-turn) missile autopilot; the effectiveness and superiority is validated by the simulation results. |
