Output-Based Robust Switching Rule Design for Uncertain Switched Affine Systems: Application to DC–DC Converters
Lingyu Zhang, Xuyang Lou, Zhan Wang
Abstract
This brief presents a new output-based robust switching control rule for switched affine systems based on observer-based feedback control or dynamic output feedback control. The designed switching rule can drive the state of the switched affine system, which have various equilibrium points, to a desired one, and overcome the effects caused by the parameter uncertainty and external disturbance. The stability conditions for the closed-loop systems are established by applying a common Lyapunov function and are presented in the form of linear matrix inequalities. Finally, physical experiments in a DC-DC boost converter circuit illustrate the effectiveness of the proposed control method.
