Abstract: A complete modal cost analysis is presented for the vibration of various kinds of simple continua with different boundary conditions. Explicit formulas for the total cost are derived for these ...

Abstract: This paper studies the controllability and observability of the system Mq̈ + Gq̇ + Kq = Bu , where M is symmetric and positive-definite, G is skew-symmetric and K is symmetric. In all cases, ...

Abstract: This paper addresses the problem of control design for large flexible space structures with uncertain modal data. The concepts of modal cost analysis are applied to flexible space structures ...

Abstract: Reduced models and reduced controllers for systems governed by matrix-second-order differential equations are obtained by retaining those modes which make the largest contributions to quadratic ...

Abstract: This paper selects sensors and actuators (location, type, and number) from an admissible set. We seek an approximate solution to this integer programming problem. Given the optimal use of the ...

Abstract: This paper proposes a redesign procedure for linear systems. We suppose that an initial satisfactory controller which yields the desired performance is given. Then both the plant and the ...

Abstract: This paper presents a methodology in the linear matrix inequality (LMI) framework to jointly optimize the linear control law and the linear parameters in the structure. The method allows the mass matrix to contain free ...

Abstract: This tutorial/survey paper: (1) provides a concise point of departure for researchers and practitioners alike wishing to assess the current state of the art in the control and monitoring of civil engineering structures; ...
