Abstract

For the problem of the existence of stochastic time delay in networked transmissions, the ARMAX-model generalized predictive control based on time stamp is proposed. The algorithm uses time-stamp to estimate the networked stochastic delays, and ARMAX model is introduced to reduce the amount of online computation, Based on the generalized predictive theory, a network delay compensator is proposed. The simulation result shows that the effects of compensation schame are good, the quality of control shows better significantly than the traditional generalized predictive control algorithm.
