Abstract

We propose the structure of a tracking electric drive with an adaptive fuzzy position controller. The computer Simulink model of a tracking triple-loop electromechanical system with an adaptive fuzzy position controller is designed. The transients for different control signals in tracking modes are provided. The indices of dynamics of an automatic tracking under different stochastic characteristics of an input position control are studied. The studies of the tracking dynamics have been held for a proportional and a proposed adaptive fuzzy position controller. The comparative analysis of the obtained quality indices demonstrated that the proposed position controller allows to implement optimal without overshoots or dragging modes laws of motion and to decrease the dynamic error in the tracking modes. The developed solutions allow increasing the accuracy and robustness of precision tracking electric drives of the positioning and tracking complexes.
