Abstract :
In this paper, dynamic feedback compensator design is proposed for the purpose of anti-windup. The design structure is based on coprime factorization of the pre-defined linear controller in the general unified anti-windup framework. Stability and performance objectives by considering the mismatch between the plant input and the controller output are represented in the form of linear matrix inequalities (LMIs). Sub-optimal LMI-based dynamic feedback compensator is got and the simulation example shows its effectiveness and demonstrates graceful performance degradation in comparison with other existing methods.
