High-performance architecture for design and analysis of robust anti-windup compensators

In this paper a general framework for the design and analysis of robust anti-windup compensators is presented. The proposed framework combines the Weston-Postlethwaite anti-windup scheme with ideas from residual generation and robust high-performance control architectures. It is shown that the framework is well connected to the Youla controller parameterization and to fault tolerant/detection schemes. Furthermore, the proposed framework provides a transparent analysis of the interactions between the different design parameters which allows for a clear design trade-off between robust stability and robust performance for the saturated and unsaturated closed-loops
