第30届中国控制与决策会议

作者： Chuanchuan Xu Qingsong Liu Center for Control Theory and Guidance Technology Harbin Institute of Technology

This paper is concerned with the stability analysis of delayed output feedback（DOF） with distributed terms implemented by numerical integration. In the process of numerical implementation, the closed-loop system becomes an infinite dimensional one and the stability of which can not be guaranteed by increasing the integration ***, it is very necessary to analyze the stability of the closed-loop systems. To this end, we first convert the closed-loop system into a standard one, which does not contain state delay in the feedback loop. Then by constructing a discretized Lyapunov-Krasovskii functional, the stability analysis problem is transformed into a linear matrix inequalities（LMIs） problem, which is convenient to be addressed.
