H ∞ Tracking Control for Switched LPV Systems With an Application to Aero-Engines

This paper focuses on the H ∞ model reference tracking control for a switched linear parameter-varying ( LPV ) model representing an aero-engine. The switched LPV aero-engine model is built based on a family of linearized models. Multiple parameter-dependent Lyapunov functions technique is used to design a tracking control law for the desirable H ∞ tracking performance. A control synthesis condition is formulated in terms of the solvability of a matrix optimization problem. Simulation result on the aero-engine model shows the feasibility and validity of the switching tracking control scheme.
