APPLICATION OF THE GENERALIZED ELECTROMECHANICAL CONVERTER THEORY TO ANALYSIS OF THE STATIC CHARACTERISTICS OF AN INDUCTION MOTOR
Purpose. The work is devoted to the development of a closed-loop control system of hydraulic transport system with pressure stabilization and its research on a mathematical model. Originality. The expediency of application of a closed-loop control system of electric water transport system with pressure stabilization as the most promising way of resource saving in the operation of pumping complexes is substantiated. The realization of the closed-loop pressure stabilization system using a discrete program regulator is proposed. The studies of parametric sensitivity of the closedloop pressure stabilization system have confirmed the high robustness of the proposed solution. Methodology. General methods of physics, hydraulics, mathematical analysis and computational mathematics were used to solve the tasks. Numerical solution of mathematical model equations and visualization of obtained results were performed in MATLAB®/Simulink environment. Results. The expediency of using closed-loop control systems of pumping units with pressure stabilization as the most promising way of resource saving in the operation of pumping complexes is substantiated. The impossibility of implementing the pressure stabilization system based on the classical PID controller is shown, which is caused by the influence of wave processes in the pipeline system with distributed parameters. The closed-loop pressure stabilization system with the use of a discrete program regulator is realized, its stability and robustness in a wide range of changes in the regulator parameters is shown. Practical value. The possibility of implementing a closed-loop pressure stabilization system of electric hydrotransport system has been substantiated; a method of calculating the discrete program pressure regulator based on the regression analysis of the results of mathematical modeling has been proposed.
