Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Implementation of Thrust Control of Electrothermal Micro-Motor at Reduction of Microaccelerations from Temperature Shock A.V. SEDELNIKOV, A.S. TANEEVA, D.I. ORLOV, V.V. SERDAKOVA, E.S. KHNYRYOVA, E.S. MATVEEVA In this work, based on the analysis of experimental data of tests of an electrothermal micromotor, as well as requirements for microaccelerations and the consequences of a temperature shock of large elastic elements of a small spacecraft, a law for controlling the thrust of an electrothermal micromotor was developed. It makes it possible to reduce the effect of temperature shock on the level of microaccelerations of the internal environment of a small spacecraft. The results are compared with the optimal control law, which ensures the maximum possible decrease in microaccelerations. The results obtained can be used in the design of control systems for small technological spacecraft. Keywords: control law, small spacecraft, electrothermal micromotor.
