Control strategies for positioning of linear induction motor: tests and discussion

The target of this paper is to establish the main problems and goals of the four most popular control strategies for induction motor drives, applied to the special case of linear motors: scalar control, direct field-oriented control (direct FOC), indirect field-oriented control (indirect FOC) and direct torque control (DTC). We introduce the peculiarities of the implementation of the different strategies for linear induction motors, the results of experimental tests of the speed controller and position controller, and a discussion of the experiments.
