| 摘 要： | 针对一类具有执行器饱和与输出约束的离散非线性时滞系统，提出新的模糊预测控制方法。首先，采用T-S模糊模型来逼近实际非线性系统，运用平行分步补偿（PDC）原理将该系统转化为一系列线性系统的凸组合。其次，通过每个采样时刻优化无穷时域的“min-max”性能指标来求解状态反馈预测控制器，得到系统满足Lyapunov渐近稳定的充分条件，并进一步将该条件转化为基于线性矩阵不等式（LMI）技术的半正定规划（SDP）问题。最后，通过数值仿真验证该方法的有效性。

| Abstract: | Aiming at a class of discrete-time nonlinear systems subject to actuator saturation and output constraint,a novel fuzzy predictive control method is proposed in this paper.Firstly,the approximation of a practical nonlinear system is realized by utilizing the T-S fuzzy model.Then,the above system is further converted into convex combinations of a series of linear subsystems by Parallel Distributed Compensation(PDC) scheme.Secondly,a state feedback predictive controller is obtained by optimizing an infinite t... |
