摘要 电流传感器受制造工艺与使用环境等因素的影响,在永磁同步电机驱动系统运行时可能失效。为提高系统的容错控制能力,该文提出一种新的基于自适应观测器的单电流传感器矢量控制策略。该策略首先在旋转坐标系下建立电流自适应观测器的数学模型,然后对唯一可测量的相电流进行坐标变换与低通滤波,计算出电流自适应观测器所需要的电流误差信息,并使用粒子群算法对观测器参数进行优化设计。半实物实时仿真结果表明与传统方法相比,所提方法具有更好的动态与稳态性能以及更高的转矩控制精度,并对电机参数具有良好的鲁棒性。

Abstract:Affected by factors such as manufacturing process and use environment, the current sensor may fail when the permanent magnet synchronous machine drive system is running. To improve the fault-tolerant control ability of the system, a new vector control strategy using a single current sensor is proposed based on the adaptive observer. First, the mathematical model of the current adaptive observer is established in the rotating reference frame; then, the coordinate transformation and low-pass filtering are carried out for the only measurable phase current to calculate the current error information, which is needed by the current adaptive observer. Finally, the particle swarm optimization (PSO) algorithm is employed to design the observer parameters. The hardware-in-the-loop real-time simulation results show that compared with the traditional method, the proposed method has better dynamic and steady-state performance, higher torque control accuracy, and good robustness to motor parameters.
