The Parameter Variation Problem in State Feedback Control Systems
(The American Society of Mechanical Engineers (ASME), 1965)The plant-parameter variation problem in multivariable linear systems described by state-vector equations is formulated using a new sensitivity measure. This formulation involves a direct comparison ... -
Hot-Gas Actuators: Some Limits on the Response Speed
(The American Society of Mechanical Engineers (ASME), 1965)A third-order model of a hot-gas position actuation system is studied in this paper. The model is assumed linear except for gas-flow saturation which is shown to place certain limits on ... -
On A Priori Statistics in Minimum-Variance Estimation Problems
(The American Society of Mechanical Engineers (ASME), 1965)Simple general formulas are derived for investigating the effect of errors in a priori statistics on the minimum-variance estimates of linear regression parameters from observations obscured by ... -
Discussion: “Precise Measurement of Clothes Insulation During Controlled Operation of the Human” (Iberall, A. S., 1960, ASME J. Basic Eng., 82, pp. 513–524)

Near Optimal Control in the Presence of Small Stochastic Perturbations
(The American Society of Mechanical Engineers (ASME), 1965)We consider the stochastic system ẋ(t) = f(x(t), u(t)) + ξ(t) where ξ(t) is a noise term, with loss criterion E 0T g(x, u)dt. A method of computing a correction to the optimal deterministic ... -
Optimum Nonlinear Control for Step and Pulse Disturbances
(The American Society of Mechanical Engineers (ASME), 1965)This paper treats the responses of a controlled system to step and pulse disturbances where the rate of change of the controlling variable is bounded. Optimum transients in the sense of ... -
On Performance Losses in Some Adaptive Control Systems: I
(The American Society of Mechanical Engineers (ASME), 1965)In controlling dynamic systems with unknown parameters and/or systems operating in unknown environment, the systems suffer due to the unknowness of pertinent parameter values, compared with ... -
On a Problem of Letov in Optimal Control
(The American Society of Mechanical Engineers (ASME), 1965)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 ... -
On the Control of Linear Systems With Pure Time Delay
(The American Society of Mechanical Engineers (ASME), 1965)A synthesis technique is developed for control systems governed by linear differential-difference equations. It is shown that such a system is equivalent to an infinite-dimensional difference ... -
Some Design Techniques for Fluid-Jet Amplifiers
(The American Society of Mechanical Engineers (ASME), 1965)The operation of the fluid-jet amplifier is described briefly. A performance criterion is developed for the amplifiers, and design techniques are presented which constrain the amplifier to exhibit ... -
A Fluid-Metering Device for Measuring Dive Rate of a Vehicle Traveling in Water
(The American Society of Mechanical Engineers (ASME), 1965)Three configurations of a small device using either incompressible or compressible fluids to indicate the dive speed of a vehicle descending in water are theoretically considered. The device is ... -
Investigation of Optimal Control With a Minimum-Fuel Consumption Criterion for a Fourth-Order Plant With Two Control Inputs; Synthesis of an Efficient Suboptimal Control
(The American Society of Mechanical Engineers (ASME), 1965)Application of Pontryagin’s optimal principle to control system problems eventually requires that a two-point boundary-value problem be solved. For plants whose equations of motion are greater ... -
The Choice of Time for Zeroing a Disturbance in a Minimum-Fuel Consumption Control Problem
(The American Society of Mechanical Engineers (ASME), 1965)The choice of time T for zeroing an initial disturbance with minimum-fuel consumption influences the dependence of the switching instances on the phase variables. For a set of discrete values ... -

Power-Transfer Characteristics for Compressible Flow From a Stationary Nozzle to a Detached Receiver
(The American Society of Mechanical Engineers (ASME), 1965)Theoretical and experimental investigations have been made of the compressible flow power-transfer characteristics from a stationary nozzle to a detached receiver. The effect of the nozzle and ... -
Successive Generation of Chebychev Approximation Solution
(The American Society of Mechanical Engineers (ASME), 1965)Problems of filtering and prediction, which are significant parts of many control problems, can be treated as those of data-fitting, usually by the method of least squares. Then, the least-square ... -
Hydraulic Speed Governor With Major Governor Problems Solved
(The American Society of Mechanical Engineers (ASME), 1965)The dashpot-type isochronous governor (which may be modified by droop) is the standard hydraulic governor in current use for prime movers. This governor is designed to give proportional-plus-integral ... -
