Abstract

This paper addresses the design of attitude controller for a fixed-wing unmanned aerial vehicle. To address the complexity of the coupled nonlinear model of a fixed-wing aircraft, this paper introduces a Fractional-Order Type-2 Fuzzy PID (FOTFPID) controller. The adoption of interval valued type-2 fuzzy sets, as an extension of conventional fuzzy sets, has endowed decision makers with the ability to assign membership and non-membership values as intervals. This enhanced capability facilitates more resilient decision-making processes. The Bat optimization algorithm is also employed to fine-tune the membership functions, scaling factors, and primary controller parameters, aiming to minimize the integrated absolute error index. Numerical simulations are conducted to demonstrate effectiveness of the proposed controllers in comparison to classical PID controllers, while subjecting the aircraft system to various disturbance conditions.

用于固定翼飞机的优化分数阶 2 型模糊 PID 姿态控制器
本文探讨了固定翼无人飞行器姿态控制器的设计。针对固定翼飞机耦合非线性模型的复杂性,本文引入了分数阶 2 型模糊 PID(FOTFPID)控制器。作为传统模糊集的扩展,区间值 2 型模糊集的采用赋予了决策者将成员值和非成员值分配为区间的能力。这种增强的能力有助于提高决策过程的弹性。此外,还采用了 Bat 优化算法对成员函数、缩放因子和主控制器参数进行微调,目的是使综合绝对误差指数最小。在飞机系统受到各种干扰的条件下,进行了数值模拟,以证明所提出的控制器与传统 PID 控制器相比的有效性。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
