Abstract

Dissertation for scientific degree of candidate of engineering science on speciality 05.13.07 – automation of control processes. – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2018. The thesis is devoted to solving the problem of multipurpose synthesis of automatic control systems of a sleeper-type point machine based on two types of linear electric motors using various optimization methods and genetic control algorithms. In the thesis a mathematical model of the point machine with the characteristic of the load is developed. The parameters of linear motors for the point machine are identified taking into account the size of the sleepers. The recommendations for changing the switch design are justified, namely, a complete transition to the translational motion, which made it possible to significantly reduce the oscillatory process in the kinematic line. The PID speed controller for the inductor linear machine was synthesized by the Chien – Hrones – Reswick method. Also the neuron position controller for the electromagnetic-type machine was synthesized by genetic algorithm methods. In the developed model prototype, the proposed algorithms for controlling the electric drive of the sleeper-type point machine are implemented. The tests of the automatic control system showed the possibility of reducing the transfer time to 0.7 seconds.
