随着吊舱推进器的发展，永磁同步电机被广泛用作船用推进电动机，但由于螺旋桨负载的复杂性，为了提高推进电机的控制性能，在全面分析直接转矩控制（DTC）策略的基础上，提出了基于滑模控制的直接转矩控制策略，控制率采用二阶滑模控制中的超螺旋算法，并证明了其在转矩和磁链控制的收敛性。分别建立传统DTC和基于滑模控制的DTC的数学模型，基于Matlab/Simulink进行仿真对比研究。结果表明，基于滑模控制的DTC相对于传统DTC，具有转矩脉动小，响应速度快，鲁棒性和抗干扰能力强等特点。
With the development of pod propeller, the permanent magnet synchronous motor is widely used as marine propulsion motor. However, due to the complexity of propeller load, in order to improve the control performance of propulsion motor, this paper fully analyzes the basis of direct torque control (DTC). In this paper, a direct torque control based on sliding mode control is proposed. The control rate uses the Super-Twisting algorithm based on second-order sliding mode, and its convergence in torque and flux control is proved. Mathematical models based on traditional DTC and DTC based on sliding mode control are established, and simulation comparison studies are carried out based on Matlab/Simulink. The results show that DTC based on sliding mode control has the characteristics of small torque pulsation, fast response, strong robustness and strong anti-interference ability compared with traditional DTC.
