Multi-Objective Optimization of a PAN-TILT System for Multirotor UAV Application

This paper presents a multi-objective optimization design method for a Pan-Tilt system based on unmanned aerial vehicle (UAV) for aerial remote sensing application. Firstly, the approximate model on the Pan-Tilt system is proposed to improve the structure optimization efficiency. The approximate model about mass and first-order modal frequency is established by using both of response surface model and radial basis function (RBF) neural network model. Then, the sensitivity analysis is conducted to determine the optimized design parameters. By the proposed way, the multi-objective optimization design is realized. At last, the modal experiments are carried out as a validation on the optimization method.
