针对一类多延时多变量网络控制系统(NCS),讨论其建模和稳定性问题.首先假设传感器采用时间驱动、控制器和执行器采用事件驱动,建立了系统在连续时域里的MIMO数学模型;然后根据Lyapunov稳定性原理和Razumikhin定理,构造系统的Lyapunov函数,并分析系统的渐近稳定性,进而得到了系统稳定的时延参数和稳定性条件;最后通过仿真实例验证了该类网络控制系统的稳定判据.
For a class of multi-delay multivariable networked control system (NCS), the modeling and stability problems are discussed.Firstly, assuming that the sensor is time-driven and the controller and actuator are event-driven, the MIMO system in continuous time domain Then the Lyapunov function of the system is constructed according to the Lyapunov stability principle and the Razumikhin theorem. The asymptotic stability of the system is analyzed, and then the stable delay parameters and the stability conditions of the system are obtained. Finally, the simulation results show that this kind of system Network Control System Stability Criteria.
