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

摘要

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.
