Decoupling algorithm in view of multivariable electrical drives control

This paper deals with decoupling algorithm in view of control of multivariable electrical drive which concern multi star synchronous motor (NSSM) supplied by PWM inverters. This electrical drive is nonlinear and multivariable. The developed approach allows using conventional regulators. Two algorithms, based on diagonalization of transfer matrix and compensation of rotating terms are established. Proposed methods are applied, to the double star synchronous machine (DSSM).
