摘要
在分析永磁同步电机的数学模型及其矢量控制原理的基础上,对永磁同步电机转子磁链定向的控制策略作了研究,针对转子磁链定向的矢量控制技术的关键问题转子磁链观测,设计了滑模转子磁链观测器,给出了基于滑模观测的控制系统,并用Matlab/Simulink进行了仿真,仿真分析结果表明该系统调速范围宽,具有良好的动态及静态性能。
On the basis of the analysis of permanent magnet synchronous motor in the mathematical model and its vector control,studied the principle of permanent magnet synchronous motor rotor flux oriented control strategy,for the rotor flux oriented vector control technology critical issues rotor flux observation,the design of sliding mode rotor flux observer,sliding mode observer was presented based on the control system with Matlab / Simulink simulation,Simulation results show that the system has wide speed range,good dynamic and static performance.
