On D-decomposition of periodically sampled systems
Journal Title: Automatyka - Year 2017, Vol 21, Issue 1
Abstract
The problem of the stability of non-uniformly sampled systems is considered. For this purpose, the D-decomposition method for determining the stability region in parameter space is investigated. Moreover, basic information about non-uniform sampling are presented, with an emphasis on periodic sampling. Based on the obtained simulation results, some comparisons of systems with different sampling patterns are considered.

Analytic method grafpol TM of synthesing sequential control systems
This paper presents the Grafpol TM method and principles of synthesising sequential control algorithms by this method, as well as examples of applying this method for modelling processes and programming PLC controllers.
Novel method to simplify Boolean functions
Most methods for determining the prime implicants of a Boolean function depend on the minterms of the function. Deviating from this philosophy, this paper presents a method that depends on maxterms (the minterms of the c...
A Comparison between Integer Order and Non-integer Order Controllers Applied to a Water Levelling System
The purpose of this paper is to compare responses of two systems with two types of controllers: integer order PI controller and non-integer order PIλ controller (FOPI). Comparison is made on the grounds of time domain re...
Supervising control system for oriented PV using weather forecasts
This paper is devoted to the problem of controlling an oriented PV using weather forecasts. The described solution presents the use of fuzzy logic fundamentals in order to increase the efficiency of a PV system. It differ...
The approximate location of imperfection in a unit circle using the spectrum of Laplace operator as a research tool
In the following article we will try to find the dependence between the location of imperfections in a closed domain and the spectrum of the Laplace operator for this region. In the theoretical part we will define the sp...
