Abstract: The paper shortly considers methods for modeling and analysis of stability and synthesis of digital and pulse-width control in linear stationary systems at a multiple discrete filtering of measurements and different types of a time delay. The paper presents the results on digital gyromoment control of a land-survey mini-satellite motion and on pulse-width control of magnetic and plasma drivers at the gyro moment cluster unloading which is economical with respect to energy and fuel expenditures.

Keywords: land-survey mini-satellite, pulse-width control, unloading.
