Good actuators in ballistic correction system can not only simplify the controller design, lower power consumption, but also can effectively improve the trajectory correctional efficiency, therefore, the design of actuators for trajectory correction control is one of important links. A kind of tail micro rotary rocket was taken as research object in this paper, then a kind of applicable fuze nose cone motor drive and gear drive actuator were designed, and a kind of drive algorithm was put forward based on the analysis of trajectory correction system for actuator output and response time on the basis of the requirement.
