摘要：In the network control system (NCS), stochastic network time-delay makes the system performance reduction and even instability. For the issue of compensation for network time-delay, this paper launced a switching control strategy based on the building of switching model of the NCS, which means to switch to a different controller according to the different intervals where network time-delay fall into. When the time-delay is less than a sampling period, the LQG of optimum control algorithm should be used with its good real-time. On the contrary, when the time-delay is larger than a sampling period, an improved and rapid GPC algorithm is pointed out. Finally, simulation result shows that this method has a good compensation effect to the network time-delay and has a very good real-time performance.
