Simulation of the LSRM dynamics comprising four-quadrant operation

This work presents a drive strategy for linear motion switched reluctance motor. Constructive aspects as well as design issues of a built prototype are presented. Static characteristics of inductance versus position and force versus position are obtained experimentally. A mathematical model is developed and used for dynamic simulations. Winding inductance profile used in the mathematical model is obtained with Fourier series representation. A control strategy that allows four-quadrant operation is proposed. Simulations of the motor operation under this strategy are carried out including starting, speed control, and speed reversal. The results shown indicate a good operational versatility from the proposed strategy.
