The invasion success of introduced plants is frequently explained as a result of competitive interactions with native flora. Although previous theory and experiments have shown that plants are largely equivalent in their competitive effects on each other, competitive nonequivalence is hypothesized to occur in interactions between native and invasive(More)
The paper deals with the cluster analysis and genetic algorithms and describes their basis. The application of genetic algorithms is focused on a cluster analysis as an optimization task. The case studies present the way of solution of two and three dimensional cluster analysis in MATLAB program with use of the Genetic Algorithm and Direct Search Toolbox.(More)
The paper deals with adaptive control of a continuous stirred tank reactor (CSTR). A nonlinear model of the process is approximated by a continuous-time external linear model. The parameters of the CT external linear model of the process are estimated using a corresponding delta model. The control system with two feedback controllers is considered. The(More)
Time-delays (dead times) occur in many processes in industry. A Toolbox in the MATLAB/SIMULINK environment was designed for identification and self-tuning control of such processes. The control algorithms are based on modifications of the Smith Predictor (SP). The designed algorithms that are included in the toolbox are suitable not only for simulation(More)
The paper deals with design of controllers for time delay systems having integrative or unstable properties. The proposed method is based on two methods of time delay approximations. The control system with two feedback controllers is considered. For design of controllers, the polynomial approach is used. Resulting continuous-time controllers obtained via(More)
Simulation is the technical discipline which shows the behavior and reactions of any system on its model. Most processes in nature have nonlinear properties and simulation is one way to examine behaviour of these systems. The behaviour is then obtained by steady-state and dynamic analysis of the model which is usually represented by a set of differential(More)
