Abstract:
|
Recent results in output-feedback controller design make possible an efficient computation of
static output-feedback controllers by solving a single-step LMI optimization problem. This new
design strategy is based on a simple transformation of variables, and it has been applied in the field
of vibration control of large structures with positive results. There are, however, some feasibility
problems that can compromise the effectiveness and applicability of the new approach. In this
paper, we present some relevant properties of the variable transformations that allow devising
an effective procedure to deal with these feasibility issues. The proposed procedure is applied
in designing a static velocity-feedback H¥ controller for the seismic protection of a five-story
building with excellent results. |
