Abstract

Тема выпускной квалификационной работы: «Настройка типовых регуляторов в условиях случайных возмущений». Исследуются возможности модификации компенсационного метода расчета типовых регуляторов, при которых будет учитываться характер случайных возмущений. Основным инструментом исследований является программная среда Matlab-Simulink. Настройки ПИ и ПИД-регуляторов находятся поисковым путем в процессе компьютерного статистического моделирования при разных отношениях запаздывания в объекте управления к постоянной времени формирующего фильтра возмущений. Сформированы аналитические модели, позволяющие рассчитывать настроечные параметры ПИ и ПИД- регуляторов с учетом информации о случайных возмущениях. Показано, что при относительно низкочастотных случайных возмущениях субоптимальные настройки параметров типовых регуляторов могут определяться по простым формулам компенсационного метода, полученным применительно к детерминированным «ступенчатым» возмущениям. Выяснено, насколько ухудшается качество управления при упрощенном «детерминированном» расчете в сравнении с расчетом, учитывающим характеристики случайных возмущений. Пояснительная записка выпускной бакалаврской работы включает в себя 65 страниц, 24 рисунка, 4 таблицы.

The possibilities of modifying the compensation method for calculating typical regulators, which will take into account the nature of random disturbances, are investigated. The main research tool is the Matlab-Simulink software environment. The settings of the PI and PID controllers are found by searching in the process of computer statistical modeling at different ratios of the delay in the control object to the time constant of the forming perturbation filter. Analytical models have been formed that allow calculating the tuning parameters of PI and PID controllers, taking into account information about random disturbances. It is shown that for relatively low-frequency random disturbances, suboptimal parameter settings of typical regulators can be determined by simple formulas of the compensation method obtained in relation to deterministic "stepwise" disturbances. It is found out how much the quality of control deteriorates with a simplified "deterministic" calculation in comparison with a calculation that takes into account the characteristics of random disturbances. The explanatory note of the final bachelor's work includes 65 pages, 24 figures, 4 tables.
