【Abstract】 The construction of variable frequency variable speed drive system for AC motor and its optimal control for energy saving is discussed in the paper. A self-seeking optimum system based on the stator current minimization criterion has been developed here. The effective information for optimal control is abstracted by the suboptimal filter recurrence formula. To organize the self-seeking optimum system, a fuzzy control is derived. The experimental results show that the certain effect in energy saving is obtained in the selfseeking optimum system when AC motor is driven under light load.更多还原
