| 摘 要： | 以永磁同步电动机的电磁关系为参考，建立了以角频率为可调参数的电流模型，并推导了基于Popov超稳定性定理的自适应率．从而提出了一种基于模型参考自适应系统MRAS（model reference adaptive system）的磁同步电动机无位置传感器控制方法。通过构建该调速系统基于Matlab／Simulink的仿真分析模型，进行了控制策略的仿真验证。分析结果表明，该控制方法具有较高的速度辨识精度，较好的稳态、动态性能和抗负载扰动能力。

Sensorless Control of PMSM Based on MRAS |
| |
| Abstract: | This paper firstly built the adjustable current model which uses the PMSM itself as a reference model with the parameter of speed of revolution adjustable. The self-adaptive law based on Popov hyperstability theory was deduced. Then a control scheme of PMSM sensorless technology based on MRAS was built. At last,the simulation under Matlab software was done. As the result of the simulation proved,this control is simple and effective,with considerable high precision in speed estimation,and also has nice steady state response and transient state response performance, besides ,it is also capable of anti-jamming with load interfere. |
