Influence of Parametric Uncertainties on Control Quality of Time-delay Processes

Popis výsledku v původním jazyce

Time-delays are mainly caused by the time required to transport mass, energy or information, but they can also be caused by processing time or accumulation. Typical examples of such processes are e.g. pumps, liquid storing tanks, distillation columns orsome types of chemical reactors. This paper deals with a design of a universal and robust digital control algorithms for control of great deal processes with time-delay. These algorithms are realized using the digital Smith Predictor (SP) based on polynomial approach - by minimization of the Linear Quadratic (LQ) criterion. For minimization of the LQ criterion is used spectral factorization principle with application of the MATLAB Polynomial Toolbox. The designed polynomial digital Smith Predictors wereverified in simulation conditions. The main contribution of this paper is an experimental simulation examination of the robustness of the designed control algorithms. The program system MATLAB/SIMULINK was used for this purpose.
