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: 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: 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 = ...

Abstract: In a series of papers [1, 2], A. M. Letov discussed an optimal regulator problem for a linear plant with bounded control variable and quadratic performance index. This problem was also discussed ...
