摘要高性能永磁同步电机控制系统对电流环的动态性能要求很高,传统的PI控制带宽有限,且易出现超调等现象,基于电流预测的无差拍控制具有较好的动态响应。为此,提出了一种在同步旋转轴系下改进时序的电流预测无差拍控制算法。通过对传统电流预测无差拍控制的时序分析,电流控制器对电流指令进行分段采样,基于永磁同步电机交直轴电压方程模型得到电压指令的补偿值,消除了原有电流指令滞后一拍的计算延时。同时,分析功率器件非理想因素与延时效应对电压状态量产生的偏差,引入电压重构算法,减小状态量误差对电流跟踪精度的影响。仿真和实验结果表明,与传统无差拍电流预测控制相比,改进后的电流预测控制算法有效地提高了电流环的动态性能和稳态精度。

Abstract：High performance control system of permanent magnet synchronous motor (PMSM) requires high dynamic performance of current loop. Traditional PI control method has limited bandwidth and is prone to overshoot. The deadbeat control algorithm based on current prediction has a good dynamic performance. Therefore, an improved deadbeat control algorithm based on timing optimization is proposed. The current controller samples the current instruction piecewise, then calculates the compensation value of the voltage instruction, thus eliminating the one beat lagging of the original current instruction. Meanwhile, the deviation of voltage caused by non-ideal factors of power devices and time delay effect is analyzed, and a voltage reconstruction algorithm is introduced to reduce the influence of instruction error on current tracking precision. Simulation and experimental results showed that the improved current prediction algorithm can effectively improve both the dynamic performance and steady-state precision of the current loop.

Key words： Permanent magnet synchronous motor current prediction deadbeat control timing optimization voltage reconstruction
