Abstract

PURPOSE: To enable an operation of providing a high speed stable response as excellent as in a level of DC and synchronous machine, by making an instruction with input current to induction motor and slip frequency detected and with a quantity of slip frequency change, in a relation of first order lead so as to cancel second order time lag characteristic of the motor, calculated.
