摘　　要：针对SRM采用传统PID或模糊控制存在转速超调量大、稳态误差大以及转矩脉动大等问题,提出基于智能积分模糊控制的直接转矩控制技术。该技术将积分器并联于模糊控制器上,并对积分器的作用时刻进行智能判别,使其在保留常规模糊控制良好动态性能的同时改善了系统的稳态精度,大大减少了系统的转矩脉动。在Matlab/Simulink环境下搭建仿真模型,仿真结果表明:基于智能积分模糊控制的直接转矩控制技术不仅能够大大减少电机的转矩脉动,而且提高了系统的调速性能和转矩响应速度并增强了系统的鲁棒性。For SRM using conventional PID or fuzzy control exists large speed overshoot, steady state error and the torque ripple and other big issue, based on intelligent integral fuzzy control of direct torque control is present. The technology will be integral in parallel on fuzzy controller, and the role of integrator time for intelligent identification, so that it reserves the conventional fuzzy control good dynamic performance while improving the system steady-state accuracy, greatly reducing the system＇s torque pulsation. The MATLAB/Simulink environment to build simulation models, simulation results show that： Integral Fuzzy Control Based on Intelligent Direct Torque Control technology not only can greatly reduce the motor torque ripple and improve the system＇s speed and torque response speed and performance enhancements the robustness of the system.
