Controller Design for the System of Parameter Uncertainty with Beidou Channel Constraints and Time-delay
This paper introduces the basic functions and structure of China's Beidou system. For a class of multiple inputs and multiple outputs system,when the control signals are transmitted via Beidou network,the phenomena of network time-delay and channel constraints will occur. In order to avoid network congestion,reduce the number of packets sent to the communication network and describe the order of controllers accessing Beidou channels,we introduce control communication sequence and establish parameter uncertainty model for the control system. To ensure the controllability of the system,we also give the method for choosing control communication matrix. Based on uncertain expressions,related principle of linear matrix inequalities and the method of Lyapunov system stability analysis,the design method for controller is given to ensure system stability. Finally,the numerical examples compare and analyze the impact of the delay and channel constraints on the control system' s dynamic performance and demonstrate the effectiveness and feasibility of the method.
