Abstract
В роботі запропоновано комплексний підхід до аналізу
чутливості систем керування за змінними стану. Продемонст-
ровано переваги систем, синтезованих методом feedback
linearization, перед системою, синтезованою методом
модального керування як з точки зору чутливості до зміни
моменту інерції другої маси, так і якості регулювання.
Проаналізовано вплив застосування ПІ-регулятора та ПІm-
регулятора в системах, синтезованих методом feedback
linearization, як на чутливість системи до зміни моменту
інерції другої маси, так і швидкодію та перерегулювання
вихідної координати.
In this work, a comprehensive approach to the sensitivity analysis of state-variable control systems is proposed. The advantages of systems synthesized by a feedback linearization method are demonstrated being compared to a system synthesized by the modal control method, both in terms of sensitivity to changes in the moment of inertia of the second mass and in terms of control quality. The influence of applying a PI controller and a PIμ-controller on the sensitivity of the system to changes in the moment of inertia of the second mass and on the speed of response and overshoot of the output coordinate in systems synthesized by the feedback linearization method is analyzed.
