Baniev I. Energyefficient Electric Drive Of Escalator Metro With Fuzzy Regulators

Object of research - static, dynamic and energetic processes in the electric subway escalator. The purpose of research - Research and development of simple, reliable, low-cost energyefficient electric drive for modernization of existing electric subway escalators that can adapt to the existing traffic management system, automation, protection and diagnostics. Research methods and apparatus - analysis and synthesis of control theory, methods of the theory of fuzzy sets using an algorithm Mamdani, numerical methods for solving systems of differential equations, computer simulation techniques. Theoretical and practical results - developed energy-efficient electric escalator installations, which minimizes the stator current of the drive motor and reduce electricity losses, as well as increases the life mechanical equipment by eliminating the electrical and mechanical shock when starting, the recommendations to replace the existing electric escalators with ladder contactor control system on the drive on the system "thyristor voltage regulator - the induction motor" with fuzzy controller. Novelty - first proposed and studied electromechanical system type "thyristor voltage regulator - induction motor with extreme fuzzy controller" under variable load; made extreme synthesis fuzzy controller, which minimizes losses in the drive, justified the use of fuzzy controller with two inputs change voltage and current at each sampling step to select the correct direction of the iterative process, as well as the appropriateness of three terms for each input linguistic variable and five for output; designed control law which minimizes the loss, the technique and the expediency of determining the width of the sound output range of linguistic variable on a simplified mathematical model, which eliminates the need to consider the nature of the pulsed voltage and current. The degree of implementation - KP «Kharkiv Metro», the learning process of the department of automated electromechanical systems NTU "KPI". Branch of service - urban electric.
