【摘要】：为满足电动汽车空调的工程需求,采用一体式电机-涡旋压缩机,研究了压缩机中永磁同步电机无位置传感器控制方案。该方案基于传统的三段式驱动方法,在开环加速与转速闭环之间,增加位置闭环的环节,以改善切换的可靠性。在闭环运行阶段,采用滑模观测器估算电机转子位置和转速,进行了大量样机实验,通过相电流、母线电流、转速、转矩和功率等多参数实验结果的互相印证,验证了控制方案的有效性和可行性。
[Abstract]:In order to meet the engineering requirements of electric automobile air conditioning, the integrated motor - scroll compressor, the compressor PMSM sensorless control scheme. The scheme method of driving three stage based on tradition, between the open loop and closed loop speed accelerated, increasing the position closed-loop links, to improve the reliability of the switch. Closed loop operation stage, to estimate the rotor position and speed of the sliding mode observer, carried out a large number of experiments, the phase current, current, speed, torque and power and other parameters of experimental results confirm each other, verify the effectiveness of the control scheme and feasibility.
