【摘要】 具有随机不确定性网络延时是网络控制系统的重要特点,也是需要解决的首要问题。本文采用灰色预测模型对网络延时建模,并根据最优化理论对其优化,结合预测函数控制实现网络控制系统的控制算法。最后使用True-time软件包和MATLAB进行算法仿真。仿真结果验证了该算法对网络控制系统各种延时具有良好的补偿效果。更多还原

【Abstract】 Having stochastic and uncertain time-delay is the critical characteristic of networked control system(NCS), also is the problem need to be solved chiefly.Grey prediction model is used in this paper to model the network delay, and optimized it with the optimization theory, combined with the predictive functional control(PFC) as control algorithm.Finally simulated the algorithm using True-time software package and MATLAB .The result demonstrated the effectiveness of this method to compensate every kinds of time delay.更多还原
