基于MPC的受约束连续时间非线性系统的拟滑模控制

Quasi-SMC based on MPC for a constrained continuous-time nonlinear system with external disturbances

Huan Meng

摘要:

针对具有外部干扰的连续时间约束非线性系统,提出了一种基于MPC的准滑模控制方法。模型预测控制问题是与QSMC的设计相关的,以产生控制输入,该控制输入可以模仿QSMC的控制过程,并保证满足状态和输入约束。同时,重构了MPC问题的费用函数,通过调整权值参数,使得基于MPC的QSMC具有更好的收敛速度。最后,通过仿真实例验证了该方法的有效性.

英文摘要:

In this article, a quasi-sliding mode control (QSMC) based on MPC is proposed for the constrained continuous-time nonlinear system with external disturbances. The MPC problem is formulated relating to the design of QSMC, to generate the control input, which can imitate the control process of QSMC and guarantee the satisfaction of state and input constraints. Meanwhile, the cost function of MPC problem is reconstructed, in which the QSMC based on MPC can show better convergence rate by tuning the weight parameters. Finally, a simulation case is provided to demonstate the effectiveness of the proposed approach.
