Transfer Function of a Time-Varying Control System Considering Actuator Inertia

Transfer Function of a Time-Varying Control System Considering Actuator Inertia Volt Avdieiev ORCID: https://orcid.org/0000-0002-9986-7637 Oles Honchar Dnipro National University Purpose. Methodological support for building an algorithm for determining the transfer function (TF) of a link, which, considering the actuator dynamics and the disturbed motion of the mass center, is equivalent on a selected trajectory section to a time-varying control system (TCS) for the rocket movement in one plane. Design / Method / Approach. TCS is modeled using differential equations with changing …
