摘要

针对传统电压型磁链观测器在对电机内普遍存在的椭圆形磁场磁链进行观测时存在稳态幅值相位误差的问题

依据稳态时磁链与感应电动势在时域的基本关系

提出了2种结构简单、易于工程实现的新型磁链观测算法。新算法在同步角频率处与纯积分具有相同的频率特性

α、β两相磁链观测不存在耦合

不再需要两相对称或感应电动势矢量与磁链矢量正交

因此能够对圆形和椭圆形磁链进行准确观测。对新算法进行了仿真

结果表明:新算法有效地消除了积分漂移

不存在稳态误差。将新算法应用于一台表贴式永磁同步电机无位置传感器调速系统的转子位置估算

并利用数字信号处理器TMS320F2812DSP对算法进行了数字化实现

结果表明:新算法在10%额定转速以上时具有良好的转速和位置跟踪效果

但在低速区估算结果不稳定; 新算法具有良好的幅值、相位观测精度

从而使系统具有良好的稳态特性; 当电机转速突变时

新算法具有良好的磁链观测精度

从而使系统具有良好的动态特性。

Abstract

Aiming at the problem that traditional flux estimation algorithms based on the voltage model would introduce magnitude and phase errors in steady state in the elliptical rotating magnetic field commonly existing in motors

two novel flux estimation algorithms were proposed based on the basic relationship between the back electromotive force(EMF)and the flux in steady state in time domain. They are simple in structure and easy to implement in industrial applications. The new algorithms have the same frequency characteristics as that of pure integrator at synchronous frequency

and there is no coupling in α and β phases. The new algorithms can estimate flux exactly either in circular rotating magnetic field or in elliptical rotating magnetic field

since neither the symmetry of the α and β phases nor the orthogonality of the flux vector and the back EMF vector is needed. Simulation results show that the new algorithms could effectively eliminate the integration drift

and realize errorless flux estimation in steady state. The new algorithms were used for the rotor position estimation in the position sensorless vector control of a surface-mounted permanent magnet synchronous motor(SPMSM). Experiment was performed using a digital signal processor TMS320F2812DSP. Experimental results show that the new algorithms have fine speed and position tracking effect when operating at a speed 10% above the rated value

but in the low-speed region

there will be unstable estimation results. The speed control system has good steady-state performance since the new algorithms can exactly estimate the magnitude and phase of flux. The speed control system also has good dynamic characteristics due to the high flux estimation accuracy of the new algorithms when the motor speed has an abrupt change.
