نویسنده
چکیده
The switching control algorithm for passing through resonance zone for the two-rotor vibration unit is proposed. The algorithm is based on speed-gradient method and leads to the significant reduction of the required level of the controlling torque. The dynamics of the overall hybrid system and its robustness against changes of spring stiffness, excentricity of rotors and damping is analyzed by computer simulation.

Modeling and Speed-gradient Control of Passage through Resonance for the Two-rotor Vibration Unit
The control algorithm for passing through resonance zone for the two-rotor vibration unit is proposed and analyzed by computer simulation. The algorithm is based on speed-gradient method and leads to the significant reduction of the required level of the controlling torque. The algorithm is simple and has only two design parameters, though the system possesses complex and, apparently, chaotic b...

1. Introduction During recent years the speed-gradient algorithms developed in control engineering area [1,2] have been applied intensively to control of oscillatory motion and particularly to control of vibration units. Among problems solved by speed-gradient approach are control of vibration units in start-up modes (swing-up and passage through resonance) [ 3-5], synchronization [6-8], etc. O...

In this paper, two kinds of vibrations are considered for a composite Timoshenko rotor: longitudinal-torsional vibration and two plane transverse one. The kinetic and potential energies and virtual work due to the gyroscopic effects are calculated and the set of six governing equations and boundary conditions are derived using Hamilton principle. Differential quadrature method (DQM) is used as ...
متن کاملSpeed-gradient Control of Passing through Resonance in One- and Two-dimensional Motion
An approach to control of passing through resonance zone based on speedgradient energy control of two subsystems (rotor and support) is presented. Two typical problems of passing through resonance for oneand two-dimensional motion of support are posed and analyzed by computer simulation. The control algorithms based on speedgradient method and averaging allow to significantly reduce the require...
متن کاملH∞ Robust Controller Design and Experimental Analysis of Active Magnetic Bearings with Flexible Rotor System
H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...
