Design of Mechatronic System for a Two-Axis Inertially Stabilized Platform in an APLI System

Abstract

Abstract-A two-axis inertially stabilized platform (ISP)with multi-sensors is designed which is used in unmanned helicopter (UH)-based airborne power line inspection (APLI) system. Based on the imaging requirements of remote sensors, an optimized mechanical system with high ratio of support load and self-weight is proposed. Meanwhile, a high precision control method is also designed. The performances of ISP including both of mechanical and control systems are tested by experiments. The results verify that the proposed design project is effective that attained the control accuracy and stability required by APLI system.

Stability Precision Error Correction of Photoelectric Detection by Unmanned Aerial Vehicle

“…The overall integrated precision model in Section 2 is used to generate real-time real pointing angles and theoretical pointing angles. Different correction models, including GFM and PM in Subsections 3.2 and 3.3, and the most commonly used models of ADRC, DAC, and CHADC in [4,12,20], are all used to calculate the correction angles. The final stability 7 Journal of Sensors precisions after correction are also compared to evaluate the performances of the correction models.…”

“…For instance, Zhuchong et al [3] developed an inertial-stabilized platform for airborne remote sensing using magnetic bearings. Zhou et al [4] presented the design of a mechatronic system for a two-axis inertial-stabilized platform in an unmanned helicopter-(UH-) based airborne power line inspection system. Dong et al [5] proposed a dynamic model and control method for a two-axis initially stabilized platform, and there are plenty of works in other fields concerning the problem of stability precession improvement [6][7][8].…”
