Design of Flight Control System Bus Controller of UAV Based on Double CAN-Bus

Abstract

This paper represents a new interconnected architecture of Flight control System (FCS). It can solve the problems of massive equipment and large cross link information. The interconnected architecture adopts double CAN-Bus to construct a redundant flight control systematic bus. This paper will illustrate the characters of double CAN-Bus comparing with the characters of CAN-Bus firstly. Then it will present the bus controller hardware design, allowance design, network communication protocol, software flow and code design respectively. The experimental results show that the bus is running well, can satisfy the small vehicle control system of a high real time capability and node demand, at the same time system has high reliability, open etc.
