Analog strategy of a receiver aircraft testbed for boom and receptacle refueling

This paper investigates the analog strategy of a self design receiver aircraft testbed for boom and receptacle refueling. The analog strategy is composed of three parts: conversion of aircraft signals and testbed signals, transformation of testbed signals and joint signals, joint servo control. Transformation of coordinates, vector synthesis are used in the conversion of aircraft signals and testbed signals. The transformation of testbed signals and joint signals adopts robotics mechanics, and the invertibility of Jacobian matrix is considered. Nonsingular time-varying terminal sliding mode controllers are designed for joint servo control systems, the controllers make the systems have better robustness, disturbance rejection properties and the tracking errors will converge to zero in finite time. MATLAB and ADAMS simulation results show that the analog strategy is effective for the receiver aircraft testbed.
