摘要
考虑电枢反应中磁饱和现象和驱动器功率管非线性特性等因素的影响,为了解决航空油泵电机相电流谐波含量大、畸变较为严重的问题,提出一种新型的相电流畸变纠正控制方法.该方法通过电流前馈幅值补偿能够基本消除各周期相电流幅值的波动,并通过迭代收敛控制,最终将相电流强制纠正为标准正弦波,从而解决了相电流畸变的难题.实验结果表明,所提出的相电流畸变纠正控制方法可以有效减少相电流幅值,提高电机系统的效率.
In order to improve current performance, a new control method is proposed to correct the distortion of phase current, in which the magnetic saturation and the nonlinear characteristic of inverters are considered. The amplitude fluctuation is eliminated by using feed forward current amplitude compensation. Meanwhile, based on iteration convergence control, the phase current is compulsorily corrected to a standard sinusoidal shape. Then, the problem of the phase current distortion is successfully solved. The experimental results show that the amplitude of phase current is reduced effectively, and the efficiency of motor system is improved.
