WebThe indirect field oriented control method is widely used for in- duction motor drives. This method needs a speed sensor such as a shaft encoder not only for the speed control but also for the torque control. The application of the speed sensor reduces the sturdiness of the system and make it expensive. Therefore, a drive system without http://article.sapub.org/10.5923.j.control.20120243.01.html
WebThe Field-Oriented Control Induction Motor Drive block represents a standard vector or rotor field-oriented control drive for induction motors. This drive features closed-loop speed control based on the indirect or feedforward vector control method.
