This paper presents a method for formulating the dynamic model of inverter-fed induction motor drive systems. An efficient model for the machine, which eliminates the time-varying terms of the inductance matrix, is used. This model has the additional advantage that can be directly interfaced with the inverter switching circuit, which is simulated in a flexible way using the state space approach. To demonstrate the efficiency of the proposed formulation, a voltage source inverter-fed induction motor drive is simulated and some transient response results are given.
