This paper addresses an interesting switching strategy of gain-scheduled controllers for linear parameter-varying systems. Unlike the conventional technique, a whole of an operating range is covered with a set of convex hulls and gain-scheduled controllers are designed one for each via linear matrix inequalities. Although a common Lyapunov function is used within each convex hull but distinct Lyapunov functions are allowed for others. We then switch from one to another in an intersection of two neighbor convex hulls online. Although switching action tends to generate non-smooth control input which may cause undesired behavior and even instability, the proposed method guarantees perfect smooth switching to avoid such behavior. An illustrated example of aircraft longitudinal motion control is included.
