Study Of Active Vibration Attenuation Based On IMC Algorithm

The vibration of the machinery or equipment on the ship has impact on the security ofthe ship structure and the comfortable life of crew. Over the years, experts and scholars in thefield of vibration attenuation technology worked hard, to find the way that can reduce thevibration.This thesis introduced the principle of active vibration attenuation technique and theresearch status of the developed countries such as Japan, South Korea, Denmark, introducedresearch situation of related organizations which is Harbin engineering university.At first, according to principle of mechanical vibration eliminator, this thesis simulatedthe vibration eliminator by using ADAMS, and printed out the data map of vibrationeliminator, and verified the rationality of the vibration eliminator. In accordance withHandbook of mechanical design design and emulate the important part of the machine, and atlast, design and make the actuator prototype.And then, according to the true environment of the vibration eliminator, design LMS forfrequency of the vibration eliminator and design IMC for phasic of the vibration eliminator,simulate the algorithm by use Simulink, making sure that is useable; Base on that, completethe designing of control program.At last, base on the experiment of the demarcator and error channel, complete theexperiment of active vibration attenuation, make sure that vibration eliminator and controlsystem is feasible.
