Electric Actuator Controller Design for Guided Missile Based on FPGA

Abstract

The electric actuator system is one of the key components in flight control system. Its performance impacts on the flight dynamic performance greatly. In order to deal with the disadvantages of the traditional electric actuator and upgrade the electric actuator system for guided missile, the electric actuator controller based on FPGA is designed. The hardware design is divided into different parts and presented in details one by one. Also the software structure is shown and its functions are introduced. The controller designed features fast response, high precision, great stability and miniaturization. Several ground tests verify its feasibility and stability, proving that it is a preferable choice for the electric actuator system in the guided missile.
