摘要
针对纯电动汽车用永磁同步电动机动态数学模型的研究,为减小电动汽车在行驶过程中的转速脉动,提高电动汽车抗干扰能力和速度快速跟踪,提出基于模糊和自抗扰控制的直接转矩控制策略。该系统模糊部分代替了传统DTC(直接转矩控制)控制中的滞环比较器和选择开关表,降低了磁链和转矩脉动,获得了更优越的性能。此外,采用自抗扰控制(ADRC)技术设计了速度控制器能实时补偿系统的扰动。仿真结果表明:基于模糊和自抗扰控制的直接转矩控制系统具有磁链和转矩脉动小、速度跟踪快和抗干扰能力强等优点。
In research of permanent magnet synchronous dynamic mathematical motor of four wheel electric vehicle,and to improve the anti-jamming performance and the speed of tracking performance,control system based on fuzzy and auto-disturbances-rejection was proposed. The fuzzy part of the system instead of hysteresis comparator and selector switching table of the traditional DTC control,reduces the magnetic chain and torque ripple and earns superior performance. The active disturbance rejection（ ADR） technology was applied to the speed controller to compensate system perturbation on real-time. Simulation results show that the controller based on fuzzy and auto-disturbances-rejection have the advantages that magnetic chain,torque ripple is small,the speed tracking fast and steady precision higher.
