摘　　要：提出采用多参数统一方法,把多个参数变化的特性综合到一个参数的变化上,用于在线实时更新永磁同步电动机转矩算法的控制参数。该参数统一方法基于电动机全状态实验同时结合实时转矩辨识控制策略在线补偿,充分考虑了电动机在磁场饱和时多个参数的非线性特性,经过实验验证,不仅实现了低速下的高精度最大转矩电流比控制,而且实现了高速弱磁下的高精度转矩控制,满足了电动汽车的应用要求。Muhi-parameter integrated control method was proposed. Multi-parameter variation＇ s characteristics were integrated into one parameter to update the control parameters of torque algorithm real-timely. This multi-parameter integrated method was on the base of all states experiment of the motor and online search. It made full account of multi-parameter＇ s nonlinear behavior. Experimental results verified that not only the precise torque control of maximum torque-per-ampere in the low speed, but also the precise torque control in the flux-weakening of high speed were carried out, which met the requirements of the electric vehicle applications.
