摘　　要：针对飞行控制系统的特点,开发了一套基于USB的多路数字信号进行波分复用的光纤传输系统,以提高光传系统的传输速率。着重构建了光发射器、光接收器及光波分复用器的物理系统。在直升机显模型跟踪电传飞行控制系统(MFCS)的基础上,开发了直升机贴地飞行波分复用光传系统实时半物理仿真验证平台。通过光传与电传性能对比,验证了所开发系统的可行性,具有工程实用意义。Aiming at the characteristics of Fly-By-Light (FBL) flight control system, a multi-channel transmission system based on USB is developed, using optical fibers as transmission media and using the wavelength division multiplexing (WDM) technology for the transmission of digital data. The goal of the system are to increase the speeds of Fly-By-Light (FBL) control system. A physical system is established, which involves optical transmitters, optical receivers and multiplexers. Based on the explicit model-following Fly-By-Wire (FBW) control system of the helicopter (MFCS), a real-time semi-physical nap-of-the-earth platform is established and a simulated fly test is processed. The feasibility and validation of this FBL flight control system can be proven through the comparision between the FBW and FBL on the above test.
