This paper proposes a double-closed-loop control method applied to stability angle of an inertial stable platform. Traditional control methods often do not consider enough the dynamic coupling of the carrier, and the control effect cannot meet expectations. This paper considers the carrier and inertial stable platform as an overall dynamic system, derives its complete dynamics and designs a corresponding sliding mode robust controller based on this. The simulation shows the control effect of angle and angular velocity, showing the advantages of this method.

摘要

This paper proposes a double-closed-loop control method applied to stability angle of an inertial stable platform. Traditional control methods often do not consider enough the dynamic coupling of the carrier, and the control effect cannot meet expectations. This paper considers the carrier and inertial stable platform as an overall dynamic system, derives its complete dynamics and designs a corresponding sliding mode robust controller based on this. The simulation shows the control effect of angle and angular velocity, showing the advantages of this method.
