Networked generalized predictive control for compensation of network-induced time delay and packet loss
面向网络诱导时延和数据包丢失补偿的网络化广义预测控制

A generalized predictive control is considered for networked control systems with time-varying networkinduced time delay and packet loss. Because multiple data are sent in one packet from the source node to the target node, and the network-induced time delay and the packet loss are known a priori, a new method is proposed to compensate the influences of network-induced time delay and packet loss on control performance using minimal prediction horizon and predictive control increment vector, respectively. Thus, we develop the corresponding networked model prediction algorithm and the algorithm of networked receding-horizon optimization. For the controlled system with unknown or slowly varying parameters, the networked feedback correction algorithm is discussed based on a modified recursive leastsquares identification algorithm. Simulation results are given to show the effectiveness of our proposed algorithms.
