摘要
针对船用六相永磁同步电机,为了研究其控制系统的性能,在基于矢量空间解耦的方法下通过矩阵变换建立六相永磁同步电机的双子空间数学模型。研究了基于Super-twisting算法的控制规律,设计了二阶滑模速度控制器,将其引入到六相永磁同步电机的矢量控制系统代替传统PI控制器,利用Matlab/Simulink工具箱对六相电机速度控制系统进行仿真研究。实验结果表明:该速度控制器能够对电机的转速环达到高效调节,且稳定性较好,相较于传统PI控制器,二阶滑模控制器能够使系统的动静态性和抗干扰性更强,速度响应更快,鲁棒性更佳。
For marine six-phase permanent magnet synchronous motors,in order to study the performance of its control system,a double subspace mathematical model of six-phase permanent magnet synchronous motor is established by matrix transformation based on vector space decoupling method. The control law based on Supertwisting algorithm is studied. The second-order sliding mode speed controller is designed. It is introduced into the vector control system of six-phase permanent magnet synchronous motor to replace the traditional PI controller. The Matlab/Simulink toolbox is used to solve the six-phase. The motor speed control system is simulated. The experimental results show that the speed controller can achieve high efficiency adjustment of the motor's speed loop,and the stability is better. Compared with the traditional PI controller,the second-order sliding mode controller can make the system dynamic and static and more anti-interference,faster speed response and better robustness.
