Modeling of Electromechanical System Modes with Fuzzy Proportional-Integral Position Regulator

Abstract

The three-circuit positional ECS with fuzzy proportional-integral position regulator has been designed. The solution for implementation of the desired indicators of dynamics and statics within the full position control range has been proposed based on fuzzy and neural network control models. The mathematical model has been obtained, with the fuzzy PI position regulator and artificial neural network being synthesized for the output signal correction. The structural Simulink-model of three-circuit positional ECS has been designed; the investigation of indicators of dynamics and statics of operative mechanism positioning modes has been performed within the full position control range. The model simulation outcomes have revealed the possibility of obtaining desired laws of operative part motion in the designed positional ECS with neurofuzzy PI position regulator during small, medium, and large displacement implementation.
