Abstract :
This work presents a drive strategy for a linear motion switched reluctance motor that attempts to control speed and the machine´s four-quadrant operation. A mathematic model is presented with the inductance shape represented by Fourier series, resulting in more realistic conditions compared with the trapezoidal inductance representation. The speed control of the motor is accomplished with PI controller whereas winding currents are controlled by a typical hysteresis controller. Results of computational simulations are shown.
