This paper presents a new constant V/f control method for induction motors and discusses the speed characteristics for steady-state and transient operations. In the proposed method, vector control is applied, and auto-boost voltage compensation for the voltage drop across the stator impedance and slip frequency compensation for improving speed control accuracy are included. The feasible operating region of the proposed method is discussed by using a vector locus. A linear model is proposed, and the stability of the V/f control system is analyzed by using the root locus to design a control parameter. The effectiveness of proposed V/f control method is demonstrated by simulation and experiment for motoring and regenerating operations.
