Control of vibrational field in a vibration unit: influence of drive dynamics

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 drive dynamics in the case when the control algorithms are designed when the drive dynamics are neglected. The performance of the closed loop mechatronic systems is examined by simulation for the model of the two-rotor vibration unit SV-2M. Comparison of simulation results for two cases (drive dynamics are neglected or taken into account) is performed.

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

“…The issues of studying the type of vibration fields for models of two-rotor mechatronic vibration units, which took into account not only the dynamics of the mechanical part of the VU, but also the dynamics of the electric drive system were considered in [Fradkov et al, 2021;Tomchina, 2019;Tomchina et al, 2019].…”

“…In this section the mathematical model of the unit SV-2 (Fig. 1) is described following [Tomchina, 2019]. Unlike [Tomchina, 2019], the elastic properties of the connection "executive motor-unbalanced rotor" are taken into account.…”

“…1) is described following [Tomchina, 2019]. Unlike [Tomchina, 2019], the elastic properties of the connection "executive motor-unbalanced rotor" are taken into account. The unit consists of two rotors 4 installed on the vibrating platform 6 elastically connected with fixed basis 2,3 by springs 7 (Fig.…”

Control of oscillations in two-rotor cyberphysical vibration units with time-varying observer

“…The proportional-integral (PI-) speed-gradient algorithm in the finite form with the objective functional (5) is as follows [Tomchina, 2019]:…”

Sliding mode control design for haptic system with vibration mode

“…Some authors has proposed conventional as well as optimal control strategy to address the stability issue [Kumar and Ohri, 2015]. In [Patrascu and Ion, 2016] uses genetic algorithm, FLC control design [Bashiti et al, 2018;Kumar and Ohri, 2017], and SMV has been used in [Kumar and Ohri, 2020b], estimation control method for nonlinear system in [Filippova, 2017], vibration method in [Tomchina, 2019] and LMI based method proposed in [Saragih, 2018]. In these articles, author have proposed the control strategy considering the delay and other uncertainty parameters.…”
