The sliding mode controller, based on the theory
of the Variable Structure System (VSS), is considered
for a robot manipulator. By consideration of VSS theory,
the nonlinear interactions of manipulator dynamics
are suppressed by use of linear sliding equations, and
VSS robustness with respect to the unknown physical manipulator
parameter...
Morphological filters have shown good performance in various image processing applications. Furthermore, their algorithms are easy to implement in special architectures, with the exception that linear filtering cannot be implemented in many of these cases. In this study, a new architecture and corresponding algorithm, capable of realizing linear shiftinvariant filters,...
"Expert systems" is an area in the field of
artificial intelligence which attempts to encode an
"expert's" heuristic knowledge and reasoning ability into
a computer program. The purpose of this study is to
investigate the applicability of using an "expert system"
in a closed-loop automatic control system.
An "expert system"...
Mathematical models for the doubly-fed machine are
presented. The properties of the machine with rotor excitation as supplied by a power converter with voltage
source character are reviewed. The peculiar torque-speed
characteristic of the machine in this operating mode and
its effect on the stability of the machine are presented....
With the development of converters and inverters, it
became possible to control the stator current of an
induction motor. The differential equations which describe
transient behavior of the induction motor are conveniently
expressed by transforming the stator and rotor variables to
d-q axes rotating at synchronous speed. The transient
behavior...
