Applied-voltage fuzzy control process for induction motors and device for performing it

摘要

The present invention relates to an applied-voltage fuzzy control process for induction motors including the following steps: measuring a speed error by comparing the current speed of an electric motor with a reference speed; generating the derivative of this speed error; measuring a power error by comparing the power supplied to the motor with a reference power; applying a fuzzy control to the speed error, to the derivative of the speed error, and to the power error so as to generate the values of a drive voltage and a power supply pulse that are suitable to drive the electric motor. The fuzzy control is divided into two sections: a first one for motor speed control and a second one for motor power control.
