The advantages of vector control provide variety of control choices in the PMSM drives. The simplest control strategy is the Zero d_axis current control (Constant Torque Operation) which is implemented in this model. The transient responses of torque, speed and 3-phase motor current are simulated.

Constructional details of various sub-modelsfor the induction motor are given and their implementation in SIMULINK is outlined. Direct-onlinestarting of a 7.5-kW induction motor is studied using the simulation model developed.
