Abstract

In the AC servo system, the output voltage is restricted by inverter output limitations. Voltage saturation occurs as a result of this limitation. The settling time of current and speed increases because of voltage saturation. This paper proposes a new control system for the rapid and stable speed response of surface permanent magnet synchronous motor (SPMSM) by using the proposed feedforward flux-weakening control based on current differential signal in the flux-weakening region. As a result of considering the current differential signal, the suppression of voltage saturation is realized with smaller d-axis current in a transient state. Finally, this paper proposes a new combination method of flux-weakening control and inverter modulation scheme, and it is possible to improve the voltage utilization on condition of the flux-weakening region. The proposed speed control system realizes the quick and stable speed and current response. The effectiveness of proposed control methods are confirmed by the experimental results under each load conditions.

基于电流差分信号的SPMSM快速稳定调速控制及扩展直流链路电压在磁链弱化区域的利用

在交流伺服系统中，输出电压受到逆变器输出限制的限制。电压饱和是这种限制的结果。由于电压饱和，电流和速度的稳定时间增加。本文提出了一种基于弱磁区电流差分信号的前馈弱磁控制方法，用于表面永磁同步电动机快速稳定的速度响应控制系统。由于考虑了电流差分信号，在瞬态下以较小的d轴电流实现了对电压饱和的抑制。最后，本文提出了一种新的弱磁控制与逆变器调制方案相结合的方法，可以在弱磁区域条件下提高电压利用率。所提出的速度控制系统实现了快速稳定的速度和电流响应。在各种负载条件下的实验结果验证了所提控制方法的有效性。
