Chapter 50 Mixed H2/H∞ Robust Controller with Degree Constraint in Angular Metric

摘要：

　　In the framework of the angular metric,robust stability margin is used to characterize the stability robustness of the closed-loop system.The mixed H2/H∞ robust controller with degree constraint is designed,whose degree is not larger than that of the plant.The characteristics of mixed H2/H∞ controller with degree constraint are discussed,and the form of the controller is parameterized.After that,we get the constraint conditions and the interpolation equations.The mixed H2/H∞ controller can be synthesized by solving the nonlinear equations,where a group preserving scheme is adapted.In comparison with the LMI controller and the central controller,the mixed H2/H∞ robust controller has the best LQG performance when the robust stability margin is given.
