In this paper a strategy to design multi-overlapping controllers for systems with longitudinal multi-overlapping structure is presented. The design process uses the inclusion principle to carry out a multi-step expansion that allows the decentralized design of a sequence of expanded local controllers. These expanded local controllers are subsequently(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)
INTRODUCTION The rate for work related accidents in the Spanish mining sector is notably higher than in other countries such as the United States. It produces a very negative impact on the mining industry. This paper is the report of a study on serious and fatal accidents in Spanish mining from 1982-2006. It is based on the reports of 212 accidents (serious(More)
In this paper, a computationally effective strategy to obtain multioverlapping controllers via the Inclusion Principle is applied to design discrete-time state-feedback multioverlapping LQR controllers for seismic protection of tall buildings. To compute the corresponding control actions, the proposed semidecentralized controllers only require state(More)
In this work, a systematic strategy to design passive damping systems for structural vibration control is presented. The proposed design methodology is based on the equivalence between decentralized static velocity-feedback controllers and passive damping systems. By using recent developments in static output-feedback control, the design of passive-damping(More)
The result contributed by this note is that controllability–observability of an original continuous-time LTI dynamic system can always be simultaneously preserved in expanded systems within the Inclusion Principle when using block structured complementary matrices. This new structure offers more degrees of freedom for the selection of specific complementary(More)
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)
