L/sub p/ input-output stability analysis of a electromotive simulation table system applying hybrid control theory

In a servo control system of the electromotive simulation table, the controller is discrete and the plant is continuous. Losing the intersample information becomes the most difficulty problem to analyze and design the system if we only depend on the traditional discrete control theory. In this paper, by using hybrid control theory, we study the L_p input-output stability of the electromotive table control system to avoid losing the intersample behavior. Firstly, we convert the control system of the electromotive simulation table into the standard sampled-data control system. Secondly, applying the lifting technique, we derive the L_p input-output stability criterion. After that, we also provide the proof of the two corollaries
