| 摘 要： | 针对常规直接转矩控制系统转矩脉冲大的缺点,提出了一种结合模糊滑模控制和空间矢量脉宽调制(SVPWM)技术的直接转矩控制系统方案。该系统用模糊滑模控制器取代常规直接转矩系统中磁链、转矩的滞环控制器,并用空间矢量脉宽技术实现系统控制。利用MATLAB建立其离散系统仿真模型,仿真结果表明:该系统能明显的减小磁链和转矩脉动,改善控制系统性能。

| Abstract: | In view of the conventional direct torque control(DTC) large torque ripple,presents a program combination of fuzzy sliding mode control and space vector pulse width modulation(SVPWM) technique for direct torque control system.The system uses fuzzy sliding mode controller instead of the conventional flux and torque hysteresis controllers,and using SVPWM technology to achieve system control。Using MATLAB to build it discrete system simulation model,simulation results show that the system can significantly reduce the flux and torque ripple and improve the control system performance. |
