基于模糊PID控制的ARUAV姿态角控制器的设计与仿真

Design and Simulation of ARUAV Attitude Angle Controller Based on Fuzzy PID Control

针对反辐射无人机(ARUAV)末制导阶段姿态角的控制器采用传统比例积分微分(PID)控制设计的精度不高、响应速度慢、超调量大等问题展开研究,提出一种基于模糊PID的控制方法。该控制方法具有精度高、响应速度快等优点。在Simulink平台上搭建了ARUAV模型,对其俯仰、滚转和航向3个通道进行模糊PID控制,并与经典PID控制进行比较。仿真结果验证了模糊PID控制能够使无人机更快达到稳态,并且能够在较小误差范围内完成对姿态角控制指令的正确响应,验证了该控制方法的有效性和合理性。

For the traditional proportional integral derivative(PID)control design of attitude angle controller in the terminal guidance stage of anti-radiation unmanned air vehicle(ARUAV),there are problems such as poor accuracy,low responding velocity,large overshoot,etc.,so this paper studies these problems,provides a control method based on fuzzy PID.The control method has advantages of high accuracy,fast responding speed,etc.This paper builds the ARUAV model on the Simulink platform,and performs fuzzy PID control to three channels:pitch,roll and heading,compares it with classic PID control.The simulation results validate that the fuzzy PID control can make the UAV reach the steady state more quickly,and can complete the correct response to the attitude angle control command within a small error range,which verifies the effectiveness and rationality of the control method.
