Time-varying observer of the supporting body velocity for vibration units

Control of Passage Through Resonance Zone for 1-Rotor Vibration Unit With Time-Varying Load

“…To study the efficiency of control algorithms for the main modes of vibration units the mechatronic vibration setups with one unbalanced rotor were developed [Blekhman et al, 1999]. Dynamics of one-rotor vibration units without taking payload and electric drives into account were studied in [Fradkov et al, 2016]. The schematics of one-rotor vibration unit with DC motor and the load, whose supporting body is oscillating in a vertical plane 0xy is shown in Fig.…”

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

“…To overcome the incompleteness of the measurements the observers or filters are used. For the vibration units with one-DOF supporting body such a study was performed [Fradkov et al, 2016].…”

“…The other works are devoted to the synthesis of observers to control the systems of magnetic levitation [Bobtsov et al, 2018], sensorless control of switched jet engines [Ortega et al, 2019] etc. In the work [Fradkov et al, 2016] a non-stationary observer was synthesized for a single-rotor vibratory unit, which restored information about the vertical speed of the platform and made it possible to implement an algorithm for passing through the resonant frequency, which was also developed on the basis of the speed gradient method.…”
