ABSTRACT:
A microcomputer based method for adjusting feedback loop gains ensures a fast, predetermined response of an induction motor drive system. A pre-computed look-up table contains gain values to be loaded into feedback regulators, the gain values corresponding to each operating point of the induction motor having the values necessary to keep the poles of the closed loop system substantially constant.
