More Information
Summary:This paper proposes the stability of delta operator systems subjected to actuator saturation by a saturation-dependent Lyapunov function. This saturation-dependent Lyapunov function captures the real-time information on the severity of actuator saturation in delta domain. Linear matrix inequalities-based methods are developed for analyzing the stability of the delta operator system. Numerical example is given to illustrate the effectiveness of the developed techniques.
