A Comparison between Integer Order and Non-integer Order Controllers Applied to a Water Levelling System
Journal Title: Automatyka - Year 2014, Vol 18, Issue 2
Abstract
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 responses of waters level in tank. In order to design both of the controllers, numerical model is established and described. Synthesis method with use of simulated annealing optimisation method is developed for each controller. In order to do a correct comparison, the two control systems have the same designing parameters. Matlab/Simulink environment and numerical model are used to do the computing. Numerically designed controllers are verified experimentally with tank system. The obtained results show that using non-integer order PIλ controller instead of a ”traditional” PI controller in simple integrating systems is useless.

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...

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 informati...
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...
