Description
Summary:The calculation of a digital regulator intended to ensure the full attenuation of free processes in a linear regulation system for a finite number of quantization periods is considered. It is shown that the full attenuation of a free process cannot be achieved for a number of sampling periods smaller than the order of the continuous part of the system. The digital regulator of the system of stabilizing the dc engine rotation frequency, an example of calculating which is discussed in this article, allows trying out a continuous setting action for two time sampling periods at the operation in the linear zone.
