摘　　要：网络控制系统中通信网络的引入,使得数据包在传输过程中不可避免地会出现数据包丢失、数据量化等现象。针对双边具有数据包丢失的非线性网络控制系统,提出一种使闭环系统稳定的H_(∞)预测控制策略。首先,利用T-S模糊方法将非线性系统转化为全局模糊线性系统,用服从伯努利分布的随机过程描述丢包模型;其次,将MPC的无穷时域滚动优化问题转化为LMI优化问题进行处理;最后,通过对H_(∞)性能指标上界的滚动优化计算每一时刻的预测控制律,以LMI不等式的方式给出使得闭环系统稳定的充分条件。The introductionof communication network in networked control system makes it inevitable to have phenomena such as packet loss and data quantization during the transmission of data packets.A H_(∞)predictive control strategy is proposed to stabilize the closed loop system for nonlinear network 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 control 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.
