摘要:
针对矢量控制永磁同步电机电流环在动态调节过程中的相互耦合问题,提出一种基于电流误差的多项式交叉耦合补偿方案。以一阶延迟的电流环为目标,在经典的d轴和q轴电流反馈控制结构的基础上,设计基于电流误差的交叉耦合补偿控制器,采用误差零点的Taylor展开式进行纯积分补偿结构的逼近,减小电压饱和效应,得到多项式结构的补偿控制器,并据此进行了误差讨论。相对于基本的电流反馈控制,该方案能够更有效地实现d轴和q轴电流在动态调节过程中的控制,尤其是提高加速过程中电流的跟踪性能。仿真和实验结果验证了该方案的可行性。
Abstract:
In order to realize decoupling control of d-and q-axis terms in current control loops of permanent magnet synchronous motor(PMSM) drives,a polynomial decoupling structure based on current errors was proposed to compensate coupling terms.To obtain one-order delay current loop,the compensation was deduced from stator voltage equations on the basis of traditional feedback current controllers.Then the integral compensation was expended to a polynomial expression by Taylor method at zero point,to red...
