Abstract

In this paper, we propose nonlinear adaptive speed control under three-phase voltage unbalance of permanent magnet synchronous motors. An adaptive control applied in a-b-c frame dynamics is proposed to compensate three-phase voltage unbalance by different values of resistance. At this method can estimate actual resistances. For velosity tracking, it is proven that the tracking error is globally asymptotically stable via Lyapunov theorem. The proposed method is performed to validate via the simulation.
相绕组电阻不平衡条件下永磁同步电机的非线性自适应速度控制
本文提出了永磁同步电动机三相电压不平衡情况下的非线性自适应调速控制。提出了一种应用于a-b-c框架动态的自适应控制方法,通过不同的电阻值来补偿三相电压不平衡。这种方法可以估计实际电阻。对于速度跟踪,利用李雅普诺夫定理证明了跟踪误差是全局渐近稳定的。通过仿真对所提方法进行了验证。
