摘要
针对航空电机在高空条件下的高效率控制问题,本文采用最大转矩电流比控制方法实现电机控制。基于转矩电流关系和交直轴电流关系分别实现了航空电机的最大转矩电流比控制,仿真分析了两种控制方法下电机的动态特性,并研究了产生不同特性的原因。结果表明,利用交直轴电流关系实现最大转矩电流比的控制方法,在输出相同电磁转矩条件下,电机定子电流更小,运行效率更高。
Aiming at the problem of high efficiency control in the aviation motor under the conditions of high altitude, the control method of Maximum Torque per Ampere (MTPA) was used in the paper to realize motor control. MTPA control of the aviation motor were realized respectively based on the relationship between torque and current, and d-axis and q-axis current. Dynamic characteristics of the motor by the two control method were simulated, and the reasons resulted in the different characteristics were studied too. Simulation results shows that under the condition of the same electromagnetic torque output, the method based on the d- axis and q-axis current can decrease the current of stator, and imorove the oneration efficiency.
