“…Passive systems perform effectively in reducing vibration caused by the vibration object when the operating frequency of the object is high. However, their performance is serious degraded in the low frequency range, reported by Owen and Jones (1986). That is, at low operating frequency the passive systems will behave as a vibration amplifier instead of a vibration reducer.…”

“…Toward this end some recent advancements in active vibration control schemes have been attempted. These recent schemes include a state space plus model velocity feedback control scheme proposed by Ross (1991); an active damping angular rate feedback control method developed by Owen and Jones (1986); and MIMO/SISO adaptive control algorithms contended by Sommerfeldt (1991), White and Cooper (1984), and Sommerfeldt and Tichy (1991), to list just a few.…”

This article presents the application of the fuzzy logic (FL) concept to the active control of a multiple degree of freedom reaction compensating platform system that is designed and used for isolating vibratory disturbances of space-based devices. The physical model used is a scaled down two-plate platform system. In this work, simulation is performed and presented. According to the desired performance specifications, a full range of investigation regarding the development of an FL stabilization controller for the system is conducted. Specifically, the study includes four stages: comprehensive dynamic modeling of the reaction compensating system; analysis of the dynamic responses of the platform system when it is subjected to various disturbances; design of an FL controller capable of filtering the vibratory disturbances transmitted to the bottom plate of the platform system; performance evaluation of the developed FL controller through computer simulations. To simplify the simulation work, the system model is linearized and the system component parameter variations are not considered. The performance of the FL controller is tested by exciting the system with an impulsive force applied at an arbitrarily chosen point on the top plate. It is shown that the proposed FL controller is robust in that the resultant active system is well stabilized when subjected to a random external disturbance. The comparative study of the performances of the FL controlled active reaction and passive reaction compensating systems also reveals that the FL controlled system achieves significant improvements in reducing vibratory accelerations over passive systems.

This paper presents the development of a general purpose fuzzy logic (FL) control methodology for isolating external vibratory disturbances of space-based devices. The physical model used is a scale-down two-plate reaction compensating platform system. According to the desired performance specifications, a full range of investigation regarding the development of an FL stabilization controller for the system is conducted. The performance of the FL controller is tested using different scenarios such as variances of passive reaction compensating components and external disturbance load. It is shown that the proposed FL controller is robust in that the resultant active system closely follows the performance of the prespecified ideal reference model. The comparative study of the performances of the FL controlled active reaction and noncontrolled passive reaction compensating systems also reveals that the FL controlled system achieves significant improvements in reducing vibrations over passive systems.
