Switched reluctance machine (SRM) has several performance advantages and broad prospect for development,but severe torque ripple limits its application greatly.In this article,the direct torque control (DTC) of SRM is studied.Firstly,the core concept of DTC is introduced,and the principle for selection of space voltage vector is given.Then,the dynamic simulation model of a 4 phase 8/6 pole SRM is built in Matlab based on combination of finite element method (FEM) and neural network (NN).Finally,the control performances of DTC are simulated and analyzed under different working conditions.Simulation results show that DTC can inhibit the torque ripple of SRM effectively,and ensure excellent abilities for speed adjustment and loading simultaneously.
