Robust Performance of Reversed-Frame Normalized Controller
反标架规范化控制器的鲁棒性能

The robust performance of reversed frame normalized controller is studied. Taking SSV(Structured Singular Value) as measure, and describing the plant, the open loop transfer function and the controller in the form of singular value decomposition, some sufficient conditions guaranteeing robust performance are drawn about the parameters of the open loop transfer function and the controller as the result of directionality and coupling analyses. This forms the theoretical basis for the design of robust controller with reversed frame normalized structure.
