Frequential Synthesis of Robust Multiple Reference Model Control

We propose here a new method to analyse and synthesize a robust controller for regulation, pursuit and stability. The design of the controller is based on the multiple reference model scheme. It comprises two reference models: a nominal one which deals with the nominal model of the plant, and a robustness reference model which is related to modelization uncertainties and robust performance index. While the nominal reference model is able to be designed by any classical way, the robustness of performances is ensured through original frequencies response constraints, so that a design procedure can be described using the Black-Nichols chart.
