摘要
以仿真一体化软件———FLSIM为基础,实现对自动驾驶仪的建模和仿真。建模从基础的状态方程开始,给出FLSIM识别的状态方程;并在此基础上,按内环(俯仰角、滚转角、偏航角)和外环(高度、航向等)控制的分类实现自动驾驶仪模型建立。通过仿真结果的静态和动态指标进行寻优仿真试验以调整模型参数,最终达到优化模型参数的目的。最后以B747为例,从建模到试验运行以及优化参数,获得其自动驾驶仪的仿真实现。证明其是灵活和方便的,于实际情况一致。
The modeling and simulation of autopilot based on integrated simulation software -FLSIM are realized in this paper. The modeling starts from the basic status equations, gives the status equations used in FLISIM. Based on such modeling, the autopilot model is founded by both the inside loop which includes pitch, roll and yaw and outer loop which includes altitude, heading and so on. By using the static and dynamic criteria of the result of simulation to do simulation test for adjusting model＇ s parameters, the purpose of optimizing model＇ s parameters is achieved at last. With B747 as an example,the simulation of its autopilot is accomplished. It is proved in practice that to study flight simulation with integrated simulation software--FLSIM method is very flexible, convenient and coincident with the practice.
