Robust stability analysis of nonlinear sampled-data control systems with time delay

Robust continuous-time control for nonlinear systems has been extensively studied over the past decades. A variety of robust controllers have been developed for a wide class of inter-connected systems. Nevertheless, it is a challenging task to digitally implement these controllers in many practical applications such as networked control systems where sampled data with possible time delay are available for feedback design. In this paper, a general framework based on input-to-state stability analysis is proposed to reveal the stability conditions for nonlinear sampled-data control systems with time delay.
