FxLMS Algorithm for Active Vibration Control of Structure By Using Inertial Damper with Displacement Constraint
نویسندگان
چکیده
Engine is the main source of vibration that generates unwanted noise and vehicle chassis. Especially, in submarine applications, radiation signatures can be detected at some distance away from using a sonar array. Thus quiet operation crucial for submarine’s survivability. This study addresses reduction force transmissibility originating engines transmitted to hull through engine mounts. An inertial damper, as an actuator hybrid mount system, addressed reduce even further level vibration. Narrow band FxLMS algorithms are broadly used cancel because its excellent performance canceling narrow noise. However, real active dampers, maximum displacement damper mass kinematically restricted. When control input signal algorithm exceeds this limitation, will collide with mechanical stops results many problems. Originated these, modified based on equalizer technique allowable proposed study. Some simulation showed propose effective suppress while ensuring given constraint.

This paper concerns Active Noise Control (ANC) of feed-forward multi-channel Filtered-x Least Mean Square (FxLMS) algorithm. The FxLMS algorithm is a preferred algorithm as a controller filter in ANC systems. In spite of its popularity, computational load in multichannel systems is a main drawback. Among the existing solutions to simplify the computations, one is based on the using only one ref...

A mathematical model of any real system is always just an approximation of the true, physical reality of the system dynamics. There are always uncertainties in the system modeling. This paper outlines a general approach to the design of an H∞ control of an active mass damper (AMD) for vibration reduction of a building with mass and stiffness uncertainties. Linear fractional transformation (LFT)...
متن کاملFuzzy Control of Seismic Structure with an Active Mass Damper
Fuzzy theory is highly promising for active structural control. The advantage of fuzzy controllers over classical controllers is the limited number of measured structural responses used to implement the control rules and its intrinsic robustness. In this paper, Fuzzy rules were generated firstly by learning from sample data obtained from the performance of the system under optimal control algor...
