Simulation study of some tracking and control methods for aircraft intercept operations
(Monterey, California. Naval Postgraduate School, 1964)
The use of radar tracking in aircraft intercept operations introduces a random noise factor into the control system. Some techniques have been proposed for organizing and smoothing the radar data prior to insertion in the ...
Root locus techniques in the log s plane for design and analysis of feedback control systems.
(Monterey, California. Naval Postgraduate School, 1964)
Root locus plots in the s plane are practically limited to a span of
two decades. In problems where some poles are very close to the origin,
while other poles or zeros are at very large values of s, sufficient
resolution ...
On-line program analysis and diagnosis.
(Monterey, California. Naval Postgraduate School, 1964)
For many program errors and program checkout problems,
on-line techniques provide a promising method of attack.
An approach developed in connection with time -sharing
computer systems is examined. Then Program Trace, ...
Analytical method for analysis and design of control systems.
(Monterey, California: U.S. Naval Postgraduate School, 1964)
A new method for design of control systems in the time domain is
presented. The adjustable parameters, the roots and the zeros of the
system are evaluated simultaneously either by hand or by computer.
The method is ...
Chromatic and spherical aberration in electrostatic lenses
(1964)
High resolution cathode-ray display devices demand focusing systems that reduce total aberration to the lowest possible value. Magnetic focusing systems have proven superior to electrostatic systems with respect to being ...
Digital control of a second order hybrid system
(Monterey, California: U.S. Naval Postgraduate School, 1964)
This paper presents the results of efforts to implement a hybrid
control system at the U. S. Naval Postgraduate School, The salient
features of this effort are use of real time digital computer programming,
digital ...
Power amplification with gate turn-off controlled rectifiers
(1964)
With ever larger amounts of power being required by present day active sonars, studies are being made towards improving the efficiency of the power train. A gain in efficiency is possible if non-linear switching type ...
Extension of the root-locus technique into three dimensions
(Monterey, California: U.S. Naval Postgraduate School, 1964)
The root-locus technique used in the determination of system response
has been a powerful tool for the engineer. Shortcomings of the technique,
however, particularly in regard to the locations of imaginary roots and
the ...
An investigation of program exchange methods for multiprogramming environment.
(Monterey, California: U.S. Naval Postgraduate School, 1964)
An investigation of program exchange techniques and methods of
evaluating such procedures is conducted. Basic hardware and system
parameters vitally affecting program exchange are discussed. The basic
program exchange ...
Linear control system optimization using a model-based index of performance
(1964)
This paper deals with a method of optimizing the free coefficients
in the characteristic equation of a linear feedback control
system. The optimization is carried out by minimizing an index
of performance associated ...
