An important challenge in the static output-feedback control context is to provide an isolated gain matrix possessing a zero-nonzero structure, mainly in problems presenting information structure constraints. Although some previous works have contributed some relevant results to this issue, a fully satisfactory solution has not yet been achieved up to now.(More)
—This note presents a strategy for choosing complementary matrices in the framework of the Inclusion Principle with state LQ optimal control of LTI systems. It is based on translating the basic restrictions given by the Inclusion Principle into explicit block structures for these matrices. The degree of freedom given by these structures is illustrated by(More)
1943 guarantees that y(t) r(t) + 1 1 + 1 c12 jx 2 (0) 0 (0) 0 kx 1 (0)j (90) for all t 0. From this proposition, it is clear that the amount of overshoot caused by the unknown x 2 (0) can be made arbitrarily small by appropriately increasing 1 and 2.

—The brief presents a reliable 1-out-2 reduced order control design strategy for a cable-stayed bridge benchmark using two overlapping subsystems and the linear quadratic Gaussian (LQG) design. Reliability with regard to controller failures is considered. Local controllers are designed for reduced order subsystems of expanded system. They are implemented(More)
