Analysis of Vibration Characteristics of PD Control Active Magnetic Bearing and Cracked Rotor System (RESEARCH NOTE)
Crack fault of rotor is one of the most prominent problems faced by magnetic bearing rotor system. In order to improve the safety performance of this kind of machinery, it is necessary to research the vibration characteristics of magnetic bearing cracked rotor system. In this paper, the stiffness model of the crack shaft element was established by the strain energy release rate (SERR) theory. T...
متن کاملOptimal Response Amplitude in an Overhung Rotor-bearing System
The optimum design of a flexible rotor supported on three-lobe bearings, overhung centrifugal compressor, is studied for the optimal unbalance response using the genetic algorithm (GA) and method of feasible directions (MFD). The MFD is used to verify the GA results. The feasibility, effectivness, and avaliability of the GA is certainly of value because it allows the exploration of many differe...
متن کاملApplication of Model Predictive Control for Improving Stability of Rotor and Controlling Active Rotor Vibration
The aim of this paper is to study the application of model predictive controller for improving stability of rotor and rotor vibration. Rotor vibrations in electrical machines are dampen out by model predictive control algorithm. The controlled system is the one dimensional Jeffcott-rotor. Model predictive control algorithm was designed, and the simulation results were obtained by Mat lab softwa...
متن کاملA Semi-Active Variable Stiffness and Damping System for Vibration Control of Civil Engineering Structures
This paper proposes a new semi-active variable stiffness and damping system (AVSD) for vibration control of civil engineering structures. The AVSD system can alter rigidity and damping of the controlled structure at each control interval to attenuate the structural responses. The composition of two hydraulic cylinder-piston systems of the AVSD system is capable of amplifying the interstory drif...
متن کاملActive Vibration Control of Gear Transmission System
In this paper, an active control structure used piezoelectric stack actuator is built to suppress vibration due to internal incentive in gear transmission. Because the gear system is timevariant and unknown, an offline modeling technique is unable to tracking the changes in the secondary path, an adaptive filter algorithm used online secondary path modeling method is proposed to the active vibr...
