The control and commissioning of high precision mechanical systems using advanced digital motion control algorithms

The study presented in this paper is centred around a VME based multiprocessor, multi-axis control system, which has wide application in high precision production machines. A mechatronics approach adopted throughout the project, which brought together many technologies, has resulted in a very dramatic improvement in system performance. The key to this improvement was finding a control strategy to reshape the overall system dynamics resulting in a much higher bandwidth and improved dynamic response. This programme of research has demonstrated that state control techniques offer a viable approach to designing distributed intelligent controls for fast acting precision servo systems. Two self commissioning strategies were implemented, the results are discussed and compared to the ´tuning parameters´ set by an experienced commissioning engineer
