H∞ Predictive Control for Network Control Systems with Packet Loss
The introductionof communication network in networked control system makes it inevi-table to have phenomena such as packet loss and data quantization during the transmission of data pack-ets.A H∞ predictive control strategy is proposed to stabilize the closed loop system for nonlinear net-work control systems with double-sided packet loss.Firstly,the nonlinear system is transformed into a global fuzzy linear system by T-S fuzzy method,and the packet loss model is described by a stochastic process obeying Bernoulli distribution.Secondly,the MPC infinite time domain rolling optimization problem is transformed into LMI optimization problem for processing.Finally,the H∞ predictive con-trol law of every moment is calculated by the rolling optimization of the upper bound of the performance index,and the sufficient conditions for the stability of the closed-loop system are given in the form of LMI inequality.
