A Consideration on the Vector Control of Induction Motor
抄録
The vector control or the field oriented control is an effective method for the torque control of induction motor. In this paper, the vector control system with controlled current source is easily obtained by using the T-I type transient equivalent circuit, because the circuit is the same as steady-state one when the amplitude of rotor flux is constant. Furthermore, the analytical solution of transient response for the vector control system is obtained for arbitrary initial conditions by using the space vector method. From the result, the torque of induction motor is proportional to the torque current command without any time lag when the initial condition is given by a steady-state value.
