Intelligent control for handling motion nonlinearity in a retrofitted machining table

  title={Intelligent control for handling motion nonlinearity in a retrofitted machining table},
  author={Shiuh-Jer Huang and C.-Y. Shy},
For low cost automation, a traditional manually operated milling machine with a lead-screw transmission system was retrofitted with an AC servo-motor. This old fashioned machining table has nonlinear time-varying behaviour caused by obvious backlash and irregular coulomb friction of the sliding surfaces. It is difficult to design an appropriate classical controller for this complicated dynamic system. Hence intelligent model-free self-organising fuzzy control and neural network control…

A theoretical and practical relation has been established between static and dynamic measuring systems and the finding of NC code modification is that for repeatable error, the authors can obtain a better dimensional accuracy for work pieces when they use a modified NC program based on the algorithms developed.

Fuzzy logic in control systems: fuzzy logic controller. II

The basic aspects of the FLC (fuzzy logic controller) decision-making logic are examined and several issues, including the definitions of a fuzzy implication, compositional operators, the interpretations of the sentence connectives 'and' and 'also', and fuzzy inference mechanisms, are investigated.

Self-organising fuzzy logic controller

A frequently used learning algorithm for self-organising fuzzy logic control has been analysed and found to be inadequate for some applications and a new approach is derived to calculate the credit value for the rule generation and modification.
