Input Bumpless Transfer Control for a Class of Switched Singular Systems

This paper investigates the stability and the input bumpless transfer performance for a class of switched singular systems. When a switching happens, by introducing a virtual reference signal, we propose the input bumpless transfer control strategy for switched singular systems to prevent the unexpected and big control bumps damaging the system. Moreover, based on the multiple Lyapunov functions, we propose a sufficient condition for switched singular systems while guaranteeing the stability and input bumpless transfer performance. In addition, a switching signal and the controller are also co-designed. Finally, in order to reveal the value and validity of the presented strategy, we used a numerical example to verify this.
