Functional Representation of Nonlinear Systems, Interpolation and Lagrange Expansion for Functionals
(The American Society of Mechanical Engineers (ASME), 1966)The paper consists principally of three parts. In the first, an original analytic representation is introduced for systems where differential equations are available. In the second, the structure ... -
Stability-Boundary Approximations for Relay-Control Systems Via a Steepest-Ascent Construction of Lyapunov Functions
(The American Society of Mechanical Engineers (ASME), 1966)This paper presents a new technique for constructing Lyapunov functions for estimating the domain of asymptotic stability of nonlinear control systems. A machine program assigns figures of merit ... -
Drift Compensation of Linear Systems by Parameter Adjustments
(The American Society of Mechanical Engineers (ASME), 1966)For a class of linear systems the conditions are given under which drift compensation is possible by adjustments of the control parameters. In such a case the system is called “completely ... -
Fluid Center-Line-Velocity Effect on Fluid-Temperature Transients in a Heat Exchanger
(The American Society of Mechanical Engineers (ASME), 1966)Inlet and outlet temperature fluctuations of the fluid passing through the inner tube of a concentric-tube counterflow heat exchanger are related by a temperature transfer function. This function ... -
On the Global Stability of a Class of Nonlinear Time-Varying Systems
(The American Society of Mechanical Engineers (ASME), 1966)In this paper the problem of the stability of motion of the equilibrium solution x1 = x2 [[ellipsis]] = xn = 0 is studied, in the sense of Lyapunov, for a class of systems represented by ... -
Multilevel Approach Applied to Control System Design
(The American Society of Mechanical Engineers (ASME), 1966)An approach to control system design is described, based on an extension of the multilevel control concept. In essence, the problem is divided into simpler subproblems: (a) The controlled process ... -
On a Class of Constrained Control, Linear Regulator Problems
(The American Society of Mechanical Engineers (ASME), 1966)An optimum control problem which can be solved completely is the linear, time-invariant free-terminal-time, regulator problem with unrestricted control function and a quadratic-type performance ... -
Uncertainty and Imprecision
(The American Society of Mechanical Engineers (ASME), 1966)The core problem in the theory of measurements is to assign a value to represent quantitatively our knowledge of a physical property, given a finite set of observations. A corollary problem ... -
