Abstract

Two common structures were often adopted to construct the photoelectric system that fixed on soft-rope hanged platform. Both of the horizontal photoelectric system and X-Y Double-Axis Gimbal photoelectric system have blind regions, so they have different application. This article regarded the photoelectric system fixed on soft-rope hanged platform as multi-rigid-body system. Lagrange equation and augmented body theory were employed to establish the balloon borne photoelectric system's dynamic model as torques that imposed on the photoelectric system were considered. Channel matrix and matrix of constraint force element and some other matrixes were used to describe the photoelectric system's dynamics. Numerical simulations have been performed to compare the two kinds of balloonborne photoelectric system's performance. According to simulation result, different application situation were given for the two structure photoelectric systems fixed on rope hanged platform. The x-y double-axis photoelectric system is adequate for tracking high-elevation object, and has better stabilization ability against pendulum disturbance. The horizontal photoelectric system was good at tracking low-elevation object and has better ability to eliminate twist torque.
