摘　　要：通常采用矢量控制结合效率最优原则来提高电动汽车异步电机驱动系统的效率,延长电动汽车的续驶里程,达到节能环保的目的。但效率优化系统由于各种干扰等不确定因素的存在,很难实现基于电机模型的准确解耦,严重影响磁通和转矩的动态性能。为此,设计了异步电机调速系统的二阶线性自抗扰控制器。线性自抗扰控制器不依赖系统的精确模型,利用扩张状态观测器估计出电机模型中的内扰和外扰并加以补偿。仿真和实验结果表明,与经典的PI控制器相比线性自抗扰控制器在效率优化的异步电机驱动系统中,具有更好的动态性能和抗干扰性能。In order to extend the trip range of electric cars,achieve the goal of energy conservation and environmental protection, SPWM combined with the optimal efficiency is the usual method. But efficiency optimization system exists serious external disturbance and various nonlinear uncertainties,so the motor model decoupling can be difficult to achieve accurately. And the magnetic flux and torque dynamic performance is affected by seriously. In order to improve dynamic performance of induction motor speed control system,designed linear ADRC to replace PI controller in efficiency optimization of asynchronous motor. LADRC don＇t depend on the precise model of system,using ESO to estimates inner and outside disturb,at the same time to compensate.Simulation and experimental results show that,the LADRC has better dynamic performance and anti-interference performance than PI controller in efficiency optimization of asynchronous motor drive system.
