摘　　要：以多功能拖轮为控制对象,提出了将动态矩阵控制(DMC)和PID控制相结合的控制方法,设计了DMC-PID串级控制器,用MATLAB对其控制效果进行仿真验证,将其结果与多功能拖轮在传统PID控制下的仿真结果进行对比分析。结果表明,与传统PID控制相比,拖轮在DMC-PID串级控制下拥有更好的控制效果,在一定程度上提高了控制系统的快速性和鲁棒性,且拥有更好的抗干扰能力。Aiming at multi-purpose tug,a new algorithm in which dynamic matrix control(DMC)is combined with PID control is proposed.It is used to design DMC-PID cascade controller for the multi-purpose tug.Its control effect is verified by MATLAB simulation and compared with the simulation results of the multi-purpose tug under the traditional PID control.The result shows that the control effects under DMC-PID cascade control are better than under PID control.To a certain extent,DMC-PID cascade control is used to improve the quickness,robustness and anti-interference ability of the dynamic positioning control system.
