Abstract: The function of switching logics is crucial to the operation of switching control systems. This paper investigates the smooth switching control approach for linear parameter varying systems, in which the control law for neighbouring subsystems is smoothly switched or scheduled in the overlapped region instead of employing the usual instant switching methods. The proposed approach is designed in terms of the achieved H^∞ performance level under control input and system output variable constraints. The control law is constructed based on the parameterised linear matrix inequality conditions. The effectiveness of the proposed approach is demonstrated by disturbance attenuation of the non-linear translational oscillator with rotational actuator systems in a quasi-linear parameter varying system representation.
