摘要
基于共轴双旋翼飞行器六自由度模型及其自身结构特点,建立了相关的动力学模型,并以该飞行器的纵向姿态控制为例,提出了一种带自动修正因子的Fuzzy-PID自适应优化方法。利用Matlab/Simulink搭建了共轴双旋翼飞行器纵向姿态控制系统模型并进行仿真,与传统PID控制和常规Fuzzy-PID控制进行了对比。实验仿真结果表明,该控制方法能够改善系统的静动态特性,具有较好的自适应能力。
Based on six degree of freedom model and its structure characteristics for the coaxial double rotor aircraft, its own related dynamics model is established, and the longitudinal attitude control of aircraft is taken for case study, a Fuzzy-PID adaptive method with automatic tuning factor is proposed in this paper. Matlab/Simulink is used to build the model of coaxial double rotor aircraft longitudinal attitude control sys- tem and compared with the traditional PID control and conventional Fuzzy-PID control. The experimental simulation results show that the static and dynamic characteristics of the system can be improved and better adaptive ability is achieved by using this method.
