| Abstract: | The sliding mode control of variable structure for a positional servo system based on the Variable Structure Control Theory is proposed. The design procedures for variable structure controllers are given and it is shown that the system is capable of keeping itself insersitive to parameter variation and external disturbance once in sliding mode motion. The mechanical characteristics have been investigated together with the electrical characteristics of a specific NC machine feed drive system. The mechanical parameters are obtained by means of system identification. Some simple sliding mode controllers have been designed and their dynamic behaviours compared. It is shown by simulation that the control system is simple in structure and easy to work out by microprocessors. |
