Comparison of Rational Approximations of Time Delay
Original language description
Real dynamical systems often show some time lag between a change of an input and the corresponding change of the output. This time lag has a whole range of causes. For needs of mathematical modelling, it is aggregated into a total phenomenon called timedelay or dead time. If a real system with time delay is modelled as a time invariant linear system, its transfer function (rational function) becomes due to time delay a transcendental function. Most of methods used for analysis and synthesis of controlsystems are developed for transfer functions in the form of rational functions only. If these methods have to be used also for dynamical systems with time delay then it is necessary to approximate transfer functions of time delay by means of rational functions. Approximations usually use either Padé approximation or Taylor series of the exponential function. A simple modification of Padé approximation is given in the contribution. It improves its time behaviour not only close to the orig
