摘　　要：在永磁同步电机(PMSM)调速系统中,提出新型模型补偿的无参数整定自抗扰控制策略.将模型辨识补偿与自抗扰控制技术相结合,采用离散最速反馈控制(fhan)函数解决了自抗扰控制器(ADRC)中非线性状态误差反馈控制律(NLSEF)参数整定的问题,使得系统结构更加简化,动态响应能力增强;引入负载观测器对负载扰动进行观测,对扰动进行部分补偿,使得速度控制系统稳态性能更好.通过仿真和实验的验证,模型补偿NMT-ADRC控制策略用于速度驱动系统具有快速的动态响应能力、转矩脉动更小、宽调速等特点,对负载及系统内部参数变化具有很强的抗扰动能力,使得该控制策略能够更好地应用于车辆驱动系统调速控制领域.A new modal-compensation without parameters tuning active-disturbance rejection controller （NMT-ADRC） was proposed in speed modulation system of permanent magnet synchronous motor （PMSM）. Model identification compensation was combined with active-disturbance rejection control （ADRC） technology. The discrete steepest feedback control function （fhan） was used to solve the problem of parameter tuning in nonlinear state error feedback control law （NLSEF）. The method simplified the system structure and improved the dynamic response capacity. The steady-state performance of speed control system became better with the introduction of load observer to measure disturbance and partial compensate for disturbance. Simulation and experimental results show that the improved model compensation NMT-ADRC speed control system has fast dynamic response capability, smaller torque ripple, wide speed range, which makes system possess strong anti-interference ability to the variation of load and internal variation of parameters. This control strategy can be better applied in speed control of vehicle driving system.
