REGION-WISE LINEAR FUZZY SLIDING MODE CONTROL OF THE MOTOR-MECHANISM SYSTEMS

In this paper, the fuzzy sliding mode controller (FSMC) and region-wise linear fuzzy sliding mode controller (RLFSMC) are applied to toggle and quick-return mechanisms, which are driven by a permanent magnet (PM) synchronous servomotor. The FSMC and RLFSMC are robust controllers developed to regulate the slider position of the coupled motor-mechanism system. These controllers are designed via a quicker and easier method in conjuction with the concept of the hitting condition. Numerical results are provided to compare these controllers and to show that the dynamic behaviour of the proposed controller-motor-mechanism systems are robust with respect to external disturbances.
