摘要: In one embodiment of the present invention, a control method for an induction motor includes calculating desired quadrature-axis voltage and direct-axis according to both current control. Below predetermined speed, is controlled in accordance with only. Above that two voltages are combined relative proportions, influence being greater higher speed. The likewise combined. thus increases increasing second speed threshold,
