Abstract: Previous studies of multi-variable servomechanism problems, using modern control theory, have relied almost exclusively on optimal control techniques to formulate and solve the problem. In that ...

Abstract: A numerical simulation of the buoyancy-induced flow around microelectronic components mounted on a circuit board has been performed using the finite element method. The circuit board is modeled ...

Abstract: The problem of assigning a physically meaningful measure of the “quality” of controllability and observability to dynamical systems which are completely controllable and/or completely observable ...

Abstract: The optimal control of dynamical systems with conventional Mayer, Lagrange, and Bolza type performance indexes has been studied in some detail [1], [2], [3]. In the present paper, the optimal ...

Abstract: This paper presents a brief review of techniques for designed-in passive damping for vibration control. Designed-in passive damping for structures is usually based on one of four damping ...

Abstract: Conventional equations for determining the variance‐covariance matrix of vertical angles, geodetic azimuths and distances are based on the standard law of propagation of covariance using the Jacobian matrix of the corresponding ...

Abstract: The following optimal regulator problem is considered: Find the scalar control function u = u(t) which minimizes the performance index J[u]= 120T〈x(t), Qx(t)〉dt, subject to the conditions ẋ = ...
