Digital Smith Predictor for Control of Unstable and Integrating Time-delay Processes

Popis výsledku v původním jazyce

Time-delays (dead time) are found in many processes in industrial practice. 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. This paper deals witha design of algorithms for digital control of the unstable and integrating time-delay processes using one suitable modification of the Smith Predictor (SP). This digital modification of the Smith Predictor is based on Linear Quadratic (LQ) method. A minimization of the quadratic criterion is realized using spectral factorization. The designed algorithms have universal usage; they are suitable for control of stable, non-minimum phase, unstable and integrative time-delay processes. The main contributionof this paper is design and simulation verification of this Smith Predictor for control of the unstable and integrative processes, because classical continuous Smith Predictors are not suitable for control of such processes. Of course, so
