| 摘 要： | 对于输入受限的离散时滞系统，提出了一种模型预测控制方法。该方法采用双模控制结构，基于Lyapunov-Krasovskii函数构造了时滞系统的终端不变椭圆集，保证闭环系统稳定性。以LMIs(Linear Matrix Inequalities)形式给出了系统稳定的充分条件，使得该方法简单，易于实现。最后通过仿真验证了本方法的有效性。

| Abstract: | A model predictive control method is proposed for the discrete-time time-delay systems with input constraints. Using dual mode control structure, the stability of the closed-loop system is guaranteed by constructing terminal invariant ellipsoid set based on Lyapunov-Krasovskii function for time-delay systems .The sufficient conditions of stability are presented in the form of LMIs(Linear Matrix Inequalities) that makes the scheme simple to be realized. The simulation results verify the effectiveness of the proposed method. |
