Induction Motor Theory

The electromagnetic torque motors are widely used in electrohydraulic servovalves. They serve to convert the control current into a proportional torque. For more details about this issue, please refer to my book:M Galal Rabie, Fluid Power Engineering, McGraw-Hill, NY, May 18, 2009, pp 336-340This...

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.

Permanent Magnet synchronous motor was modeled with the help of vector control technique and it was also made sensorless based on sliding model observer (SMO). controller parameters are given after tuning it with conventional gradient descent method.
