Abstract
A design approach is presented to uniquely couple passive and active control designs of structures and to solve the resultant problem using multiobjective optimization techniques. Passive control is realized through structural modifications while active control is accomplished by negative state feedback control to drive the characteristic poles of the system into a desired region in the complex plane. It is observed that it is advantageous to use multiobjective optimization strategies to better correlate between passive and active control designs thereby providing the designer with a powerful tool in finding a good balance between possibly conflicting practical control limitations.
