Design and application of H-infinity robust controller for multi-model switching system
多模型切换系统H∞鲁棒控制器的设计与应用

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.
