Digital Position Servo System: A State Variable Feedback System
Philippe Mota, J.P. Rognon, Hoang Le‐Huy · IEEE Transactions on Industry Applications · 1984
A digital position control system using a dc motor fed by a four-quadrant transistor chopper is presented. All control functions are handled by a microcomputer requiring only an incremental encoder for position and speed sensing. Two control approaches are considered: the classical control approach and the state feedback approach. For each approach, static and dynamic control performance is studied in terms of system parameters. Experimental-results are given and discussed.
