Abstract
Aiming at strong electromagnetic interference has big influence on four-rotor heading angle
analyze deficiencies of methods that most literatures suggest
propose a method of using support vector machine( SVM)based on particle swarm optimization( PSO). The input of the modle is the heading angle that is measured in strong electromagnetic interference
and the desired angle is the output. Through the simulation with the collected data
the results show that the model is reliable and greatly improving the accuracy of the heading angle.
