| Summary: | This paper deals with the issues of developing a control system of
a spacecraft solar array drive assembly actuator that meets strict requirements for operation at the set angular accelerations and
rotation velocities, under the influence of payload and disturbance
forces. The work consists of developing a control system, its
mathematical description, simulation and fabrication of an assembly
prototype that meets the defined technical specifications. In the
work, methods of mathematical and experimental investigation
are applied. System mathematical simulation was carried out using
the Matlab/Simulink applied software. As a result of the work, a
structural diagram is proposed of the control system of a spacecraft
SADA actuator of an operating follow-up system based on the
set angular position that is calculated as required for operation
at the defined angular accelerations and rotation velocities. The
article presents the results of mathematical simulation of actuator
operation, the results obtained during operation at the defined
angular rotation velocity by a prototype SADA, the analysis and
comparison of theoretical and practical results. Experimental
investigation shows the achievement of the goal when developing
the actuator control system, as well as rather exact matching of
simulation and experiment results. The proposed control system
can be used when designing and developing devices with similar
technical specifications. |
