Abstract

A dynamic absorber with DC servo motors for actuation is designed and built as an actively suppressing vibration system. This is a two-stage spring-lumped mass system with sliding guide. Each mass has an internal vibration source. The discrete time state space model is identified from the input and output data of this system by using a modified recursive least square method. Then a multivariable adaptive control strategy is derived by combining the concept of the pole assignment with a multivariable stability theorem. Finally, the feasibility of employing this control method is evaluated based upon experimental results.
