Abstract :
The permanent magnet stepper motor is considered for use in high-performance positioning systems. A model-based control law is developed using the exact linearization methodology and implemented on an industrial setup. The practical issues of speed estimation and voltage saturation are considered and resolved through the use of a nonlinear observer and field-weakening, respectively. The results of the implementation of the control algorithm for an industry-specified point-to-point move of a linear positioning table are presented and discussed
