摘要
在电传动装甲车辆用永磁同步电动机的控制中,在恒转矩区和弱磁区内采用不同的控制算法,导致控制结构复杂、速度切换不平滑。针对该问题,提出一种基于磁链的定子电流定向控制方法,并基于dSPACE构建了驱动系统的快速控制原型仿真系统,对控制算法进行了多种工况下的仿真试验验证。试验结果表明,控制算法能够快速、无差地跟踪速度给定信号,避免了恒转矩控制和弱磁控制的变结构切换问题,并验证了快速控制原型仿真系统的可用性和仿真可信度。
For the control of PMSM in electric drive armored vehicle, the control algorithms are usually different for permanent torque control and flux-weakening control, and the structure is complicated and the speed changes unsmoothly. A kind of stator current orientation control algorithm based on flux was provided, and the optimization algorithm on torque control was designed by MATLAB. The RCP simulation platform based on dSPACE was built, and the real-time simulation was carried out. The simulation results show that this control algorithm is effective in smoothing the speed between perma- nent torque control area and flux-weakening control area.
