Cessna-172P自动驾驶机翼水平调整器Ziegler-Nichols PID控制方法

摘要

针对Cessna-172P自动驾驶机翼水平调整器PID控制参数设计离线工作量大的问题,提出了Ziegler-Nichols PID控制方法.Ziegler-Nichols PID控制器的自适应过程不需要系统的任何先验知识,也不需要建立任何对象模型,可以保证控制回路始终运行在最佳状态.设计方法通过对Cessna-172P自动驾驶机翼水平调整器达到自适应控制,结合JSBSim飞行仿真系统对其进行初步仿真.仿真实验结果证明,所设计的驾驶机翼水平调整器在全局范围内具有良好的动态响应性能.%In order to solve the chosen problem of Cessna-172P autopilot wing leveler PID control parameters,Ziegler-Nich?ols method is proposed. Ziegler-Nichols PID controller the adaptive PID controller doesn't need any prior knowledge of the process and build any process model,and can keep the control loop operating efficiently. The method can control Cessna-172P autopilot wing leveler adaptively,which is implemented in JSBSim flight simulation system. Simulation experiments display the controller has a better dynamic respond performance in overall situation.
