Control of vibrational field in an elastic vibration unit with DC motors and time-varying observer

Abstract

In the paper the problem of feedback control of vibrational fields in a vibration unit is analyzed taking into account the influence of the elasticity of cardan shafts, the drive dynamics, saturation for control torques. In addition, the synthesized rotor synchronization control algorithm uses the estimates of a non-stationary observer, which makes it possible to implement it practically on a two-rotor vibration unit SV-2. The performance of the closed loop mechatronic systems is examined by simulation for the model of the two-rotor vibration unit SV-2.

Design of optimal-robust control of step motors with partially unknown parameters and disturbances

“…At the present moment, step motors are being replaced by AC machines, since the latter ones have a long service life and reliability due to the absence of sliding electrical contacts [Viorel and Lorand, 1998;Gieras et al, 2016]. Electric motors are used to study various physical phenomena [Mihalache et al, 2013;AL-Sabbagh and Mahdi, 2010;Kelemen and Crivii, 1975;Boikov et al, 2016;Tomchina, 2021;Ugalde-Loo et al, 2013].…”

Overview of models and control methods for step motors and permanent magnet motors

“…Currently, DC collector motors are being replaced by AC machines, since the latter ones have a long service life and reliability due to the absence of sliding electrical contacts [Viorel and Lorand, 1998;Gieras et al, 2016]. Electric motors are used to study various physical phenomena [Boikov et al, 2016;Tomchina, 2021;Ugalde-Loo et al, 2013]. In aviation and space technology, AC machines are actively used in actuating systems, such as drives for opening large structures, guidance and stabilization systems, etc [Sarhan et al, 2009;Fu et al, 2022].…”
