具有最小转矩脉动的无刷直流电机驱动实时最大转矩电流比控制

A nonlinear control scheme is proposed for real-time tracking of maximum torque per ampere trajectory of the surface-mounted brushless dc motor with non-sinusoidal back electromotive force (back-EMF). The strategy employs the Lagrange's Theorem to obtain the optimum stator current, at which both torque ripple and corresponding current magnitude become minimized. A new maximum torque per ampere (MT...
