摘要
对于时变系统，目前常用的控制器设计方法为定点法，该方法虽然具有设计思路简单清晰，设计理论工具丰富等优点，但其计算量大，实际控制效果与定点设计控制效果存在差别，有时还可能导致系统失稳．在此，揭示了定点法所存在的问题及其实质。
Fixed point method is widely employed in engineering applications of controller design for time varying system. Although this method has many advantages, such as its clear design routine and the wealthy linear control theory to support, there exists many drawbacks, such as the excessive calculation and its ad hoc scheduling strategy. Scheduling variables being time varying, the controllers designed by the fixed point method often made the closed systems act with lower performance than the fixed point design objectives, even result unstability. The essence of these drawbacks is disclosed in this paper. Aiming to overcome these drawbacks, the modern method, especially the H ∞ based method, is employed to design the gain scheduling controller. The results show the potential of the modern method dealing with the scheduling controller design.
