Journal Title: Електромеханічні і енергозберігаючі системи - Year 2017, Vol 3, Issue 39
Abstract
Purpose. The nonlinear fuzzy controller modeling that implements slip modes and the investigation of an electromechanical system with compensation of perturbing influences. Methodology. The optimal control methods theory is used for the development of control algorithms for electric drives by the criteria of maximum speed, minimum dynamic loads, minimum energy; the construction of a structural diagram of the system under investigation, both with computer simulation method for testing the effectiveness of mathematical models. Results. The research of the electromechanical system including a mastering model, a nonlinear fuzzy controller and an object of control in the form of an elastic-viscous two-mass system with a DC electric drive has been performed, and the system has been shown to be highly efficient for the accurate reproduction of optimal giving signals to control objects under disturbing influences. Originality. For the first time, the structure of the odd regulator is developed, which is based on the use of its adaptive properties, to ensure the required positioning accuracy with varying parameters and load, which provides a weak sensitivity of the control system to parametric disturbances. Practical value. The developed control system with fuzzy correction of the specified speed diagrams ensures the realization of these diagrams in the optimal high-speed and dynamic loads mode under the action of parametric and external disturbances, using a slip mode.
