Abstract:
|
In this paper, the design and performance of partial-state controllers with incomplete
multi-actuation systems for the seismic protection of tall buildings is investigated. The proposed
approach considers a partially instrumented multi-story building with an incomplete system of
interstory force-actuation devices implemented at selected levels of the building, and an associated
set of collocated sensors that measure the interstory drifts and velocities corresponding to
the instrumented stories. The main elements of the proposed controller design methodology are
presented by means of a twenty-story building with two different actuation schemes. For these
control configurations, partial-state controllers are designed following a static output-feedback
H8 controller design approach, and the corresponding frequency and time responses are investigated.
The obtained results clearly indicate that the proposed partial-state controllers
are effective in mitigating the building seismic response. They also show up that a suitable
distribution of the instrumented stories is a relevant factor in the control system design. |
