摘　　要：电机模拟器耦合电感参数对系统性能影响大,但其参数选型被详细分析研究得较少。对此,文章提出电机模拟器耦合电感参数快速选型方法。其首先通过理论分析,计算出电感参数的大致选型范围;然后对系统控制器设计进行分析,同时在某典型电机上进行仿真验证,并结合计算参数范围及仿真结果选择最优电感参数;最后在选定电感参数下对不同开关频率对系统电流误差的影响进行研究,解决了开关频率的快速选择问题。仿真及分析结果显示,在合理选取解耦电感参数的前提下,当模拟器开关频率达到被测变流器开关频率的10~20倍时,能保证全速度段下的电流误差不超过5%。The coupling inductance parameters of motor simulator have a great influence on the system performance,however,there is limited detailed analysis and research of their parameter selection.This paper proposes a method for quickly selecting inductance parameters.Firstly,an approximate selection range of inductance parameters is calculated through theoretical analysis.Then,the system controller design is analyzed and verified by simulation on a certain type of motor.The optimal inductance parameter is selected in consideration of the range of calculation parameters and simulation results.Finally,the influence of different switching frequencies on the system current errors is studied under the selected inductance parameters.This approach to quickly select switching frequencies was simulated.The simulation and analysis results show that,a switching frequency of the simulator reaching 10-20 times that of the tested converter can guarantee current errors less than 5%in the speed range,provided that decoupling inductance parameters are reasonably selected.
