Abstract. Two methods for selecting the transfer function of a discrete correction filter are considered. With a simpler method, the control effect is significantly reduced, but the speed error increases. A more complex method of correction filter selection enables the speed error retention, as in the case of minimum damping time of the free process, but with a less significant reduction in the control effect and a small overshoot when working out the jump. An example of digital tracking system calculating is given. Numerical simulation of the calculated CSR in the MatLab system is performed for linearly increasing and stepwise reference signals. The simulation data are reported to coincide with the calculated results.
Keywords: digital tracking system, free process decay, transition time exceeding minimum
