ROBUST GAIN-SCHEDULED PID CONTROLLER DESIGN FOR UNCERTAIN LPV SYSTEMS
Vojtech Veselư – Adrian Ilka
A novel methodology is proposed for robust gain-scheduled PID controller design for uncertain LPV systems. The proposed design procedure is based on the parameter-dependent quadratic stability approach. A new uncertain LPV system model has been introduced in this paper. To access the performance quality the approach of a parameter varying guaranteed cost is used which allowed to reach for different working points desired performance. Numerical examples show the benefit of the proposed method.
