Low-cost Actuator Controller Design for UAV Airborne Guided Missile Based on STC MCU

Abstract

As the servo actuator, the actuator system is of great significance in the guided missile. Its performance plays a key role in the hit accuracy of the guided missile. For the simple reason that the guided missile is a one-time military device, low cost and high stability is the top concern in the design of guided missile. In order to meet the requirement above, the actuator controller based on STC MCU is designed in this paper. The hardware design is introduced in details one circuit by one circuit. Meanwhile, the software design is presented too. The controller designed is highly stable and relatively cheap. Several flight tests prove that it is a reasonable choice for the low-cost actuator system in the guided missile.
