✦ Synopsis

The problem of reassigning some poles of a vibratory system, while keeping the other poles unchanged, is considered. The problem may be solved uniquely by single-input state feedback control. A family of solutions to the partial pole assignment problem may be obtained by applying multi-input control forces. An algorithm for determining a multi-input control which is small in some sense is presented. The non-iterative algorithm proposed, de"nes a closed-form solution to the partial pole assignment problem in its natural second order form, and no "rst order realization is used. The reduction in the control e!ort achieved by the proposed method is demonstrated by numerical examples.

A new method of simultaneous pole assignment and simultaneous stabilization of h plant models Pi (j = 1, . . . , h) by multirate sampled-data controllers is presented. The method is based upon two key ideas. The first is the introduction of the 'perturbation structure' assumption on the plant model
