Closed-loop actuator identification for Brazilian Thrust Vector Control development

Abstract

© 2016This paper presents the current status of the development of a Thrust Vector Control system for new Brazilian launch vehicles, looking for the highest performance by closed-loop servo hydraulic actuator identification. Therefore, a test environment with a mass-spring test bench is introduced. Engineering models of two different types of actuators, three-way and four-way valve controlled pistons with direct drive control valves are developed. The dynamic responses are experimentally determined and subsequently mathematically modeled.
