摘　　要：针对一类输入受限的线性离散时滞系统,提出一种在线求解局部控制器的有限时域预测控制方法,使得系统的吸引域扩大,而且在终端约束集内控制器基于记忆状态反馈,这样能保证系统状态平稳、快速的趋向原点。最后采用线性矩阵不等式(LMI)方法给出了主要结果,并且仿真验证了该方法的有效性。For a class of input-constrained linear discrete systems with time-delay, a kind of the finite horizon model predictive method for obtaining a local controller online is proposed, which enlarges the attractive region. Furthermore, the controller that takes use of the memorial state feedback in the terminal constraint set makes system state stable and converges to the origin rapidly. Finally, the main result is given by means of linear matrix inequalities （LMI）. Simulation are presented to demonstrate the effectiveness of the method.
