| Abstract |
Modern compensation circuits are built with the
use of controlled sources. Such circuits provide for many
possibilities, which are not fully used due to the lack of
appropriate algorithms of source control. Some algorithms for
optimal control of compensators require the knowledge of
circular parametric operators that describe linear periodically
time-varying or non-linear impedance elements of the circuit i.e.
load impedance and inner source impedance. The operators are
not known in practice. Thus, an attempt has been made to create
an algorithm for identification of the operators based on terminal
signal measurements of voltage and current.
The manner of representation of linear two-terminals with
periodically variable parameters has been described in the paper.
This has been achieved by means of a circular parametric
operator, which assumes the form of a matrix of real elements in
the domain of time. The paper presents the derivation and effects
of a genuine algorithm for identification of circular parametric
operators describing performance of periodically time-varying
systems, of one input – one output type. The algorithm has been
connected with the algorithm for indication of optimal currents
in one-phase circuits of “real source – receiver” type (Fig. 1.)
Apart from theoretical considerations, the paper also presents
some results of computer simulations.
