Controller design method for CSIM drives operating under different control strategies

Abstract

A general linear method is described for controller design for a speed-controlled current-source induction motor (CSIM) operating under two different control strategies: slip frequency control (SFC) and torque angle control (TAC). The designed controller ensures asymptotic stability and satisfactory dynamic response of the electric drive system. Digital simulations of the original nonlinear system operating under the two control concepts were carried out, and the validity of the design was confirmed. Results obtained from the electric drive systems controlled by the two schemes were compared and practical conclusion mentioned.<>
