Model following control of nonlinear sampled-data systems by Lyapunov-based redesign

This paper deals with a discrete-time design of model following control for nonlinear systems. When a digital computer is used as a controller, a continuous-time plant is usually controlled by holding the value of the control signal constant during the sampling periods. This method is simple and frequently used. However, it sometimes leads to problems of instability or poor control performance. This study shows a design method of a model following controller by a Lyapnov-based redesign approach with the improved Euler model on the basis of the idea of the sampled-data controller design by Nesic et al.
