摘要
针对三自由度直升机系统的不稳定性、非线性、强耦合等特点,设计了模糊积分控制算法,进行了直升机模型的飞行姿态控制研究。基于MATLAB的仿真平台,进行模糊积分控制的直升机系统仿真研究,分析了系统的鲁棒性和抗干扰性,并与传统的PID控制算法进行比较,仿真结果表明,模糊积分控制算法能够有效地控制三自由度直升机模型的飞行姿态,并且具有良好的动态品质,较好的鲁棒性和抗干扰能力。
In view of the instability,nonlinearity and tight coupling of three degrees of freedom helicopter system,a study on flight attitude control system of helicopter model has been done,with the use of fuzzy integration controller algorithm. Based on MATLAB simulation platform,a fuzzy integration control algorithm is studied for helicopter system,analyzed the robustness and anti-interference ability of the system,while comparing it with the traditional PID control algorithm. The result shows that the fuzzy integration control algorithm can effectively control the flight attitude of three degrees of freedom helicopter model,and has favorable dynamic quality,robustness and anti-interference ability.
