Active Vibration Control of a Motor System by H ∞ Control

Torsional vibration suppression of drive system based on DMC method

“…Under the situation of no considering constraint, the above-mentioned problems are the minimal optimizations problems least optimization under dynamic model (8) and takes ǻu M (k)=[ǻu(k),…,ǻu(k+M-1)] as optimization variables. Therefore, the model (8) can be rewritten as vector form to solution the problem.…”

“…The shaft torsional vibration is often generated when a motor and a load are connected with a flexible shaft. The torsional vibration suppression and disturbance rejection in rotating mechanical drive system become an important problem to be solved [8][9][10] . Such a system is called as the two-mass resonant system and this paper treats the vibration suppression control of this system.…”

Vibration Suppression Using Vibration Coordinate System Based on dq Transform with Specific Frequency

“…In this about three decades and more, many kinds of vibration suppression methods have been proposed by using various mathematical techniques. Controllers using sliding mode control [2] [3], H ∞ control for the resonant vibration [4], and disturbance observer(DOB) [5] [6] [7] [8] have been proposed. Furthermore, an adaptive feedfoward cancellation(AFC) [9], a repetitive controller [10], and specific component reduction controller(SCRC) [11] have been proposed for suppressing the vibration caused by the periodic disturbance, the resonance, and others at the specific frequency.…”
