Abstract

This paper presents a design method of feedback gain for a network-based control system based on inverter parallel operation. The controller stabilizes the plant in the presence of time-delay less than one control period. According to the theory of asynchronous dynamical system, principle of Lyapunov stability and method of linear matrix inequality is presented. Moreover the model for control feedback network-based system with random time-delay is built and the modified feedback controller is designed. Experimental results show the effectiveness of the feedback control method.
