Model-Free Adaptive Predictive Control for Networked Control Systems with Dual-Channel Packet Loss

摘要

In order to reduce the impact of network communication on networked control system (NCS), a networked model-free adaptive predictive control scheme is proposed for networked control systems with random packet loss in the forward and feedback channels. The data model based on the I/O data dynamic linearization is used as the predictive model. It is a data driven predictive control method and it is independent of the mathematical model for the controlled object. To suppress the system oscillation caused by packet loss and the frequent change of the expected signal, an improved MFAPC method was proposed. Finally, the effectiveness of the improved MFAPC method for packet loss was verified by simulation.
