横向磁通开关磁阻电机间接位置检测方法

Indirect Position Estimation Method of Transverse Flux Switched Reluctance Motor

提出一种横向磁通开关磁阻电机间接位置检测方法,实现TFSRM起动相的确定及低速运行时正确换相。起动时各相同时注入高频脉冲电压,计算出电感值,再由逻辑关系确定起动相;在低速运行时,对下一导通相注入高频脉冲电压,同时检测该相电流,当相电流达到换相阈值后即可执行换相。该方法无需大量计算、算法简单。最后在MATLAB环境下建立了三相TFSRM系统的仿真模型,并进行了仿真,仿真结果验证了该方法的可行性。

A transverse flux switched reluctance motor indirect position detection method was proposed,and TFSRM starting phase determination and correct phase switching during low speed running were realized. High frequency pulse voltages were injected to each phase at the same time when starting,the inductance value was calculated,and the starting phase was determined by the logical. When running at low speed,high- frequency pulse voltage was injected to the next phase,and detecting the phase current at the same time,when the phase current arrived to the reversing valve,switching phase was executed. This method needs not a lot of calculation with simple algorithm. Finally the TFSRM three- phase system model was established in MATLAB environment. The simulation results show that the method is feasible.
