Gain Scheduling Output Feedback Controller Design for Saturated Linear Plants

摘要

In this paper, we will study the control design problem for linear systems subject to actuator saturations from a gainscheduling perspective. A feedback controller, expressed in the form of linear fractional transformation, is proposed to guarantee stability of the closed-loop system as well as providing disturbance/error attenuation measured in L2 norm. The synthesis condition is cast as a convex optimization problem in terms of linear matrix inequalities (LMIs) and can be solved ef.ciently. Numerical examples are provided to demonstrate the proposed saturation control approach.
