摘　　要：开发了一种多路数字信息进行波分复用的光纤传输系统。着重构建光发射端机、光接收端机及光波分复用器的物理系统, 提高了飞控系统信号的传输速率, 减少误码率。在具有良好解耦及动特性的直升机显模型跟踪电传飞行控制系统(MFCS)的基础上, 进行了直升机贴地飞行的地形回避半物理仿真。通过光传与电传性能对比, 验证了所开发的波分复用光传飞行控制系统的可行性, 具有工程实用意义。A multi-channel transmission system is developed, using optical fibers as transmission media and using the wavelength division multiplexing (WDM) technology for the transmission of digital data. A physical system is established, which involves optical transmitters, optical receivers and multiplexers. The goals of the system are to increase the speeds of the data transmission and to decrease the miscoding. Based on the explicit model-following Fly-By-Wire (FBW) control system (MFCS) of the helicopter, which has an excellent performance on four-channel decoupling and dynamic following, a real-time semi-physical nap-of-the-earth platform is established and a simulated fly test (slalom) 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 test.
