Abstract:At present, in the field of aerospace, electric servo system is more and more used in rocket vectored thrust control, aircraft and missile rudder control, aircraft turning and braking control and so on. Electric servo system as the key part of aircraft control system, its performance directly affects the vehicle maneuverability, generally require small overshoot, fast response, strong ability to resist load disturbance, good real-time, etc. The research object of this article is a set of space electric servo control system, namely the drive control part of space electric servo system, mainly from the software control strategy and design of the hardware composition of the electric servo control system are introduced the design thought and its superiority.
