Fuzzy Control Of An Unmanned Reconnaissance Plane To The Stability Of The Platform At The Applied Research

In the Unmanned Aerial Vehicle(UAV) reconnaissance system, the optical sensors are usually installed on the stabilized platform in order to counteract the influence of angular motion of aircraft such that steady images can be acquired by optical sensors on UAV.This article introduces the UAV stabilized platform on the structure and principle, and then based on the moment of momentum theorem and brother's rotation theorem, respectively, set up a two-axis stabilized platform and the dynamic equations of three-axis stabilized platform for dynamic equation. In addition, the control plane exercise with a combination of platform, derived from the plane under the platform of sports performance equation of motion and exercise in the plane as a platform for the control of interference.Without taking into account cross-coupling, the three-axis stabilized platform and the two-axis stabilized platform stability in the channel loop structure similar to this paper, only the two-axis stabilized platform pitch channel as an example, set up a pitch-channel platform stabilization loop mathematical model , citing two-axle platform pitch channel kinetic equation, add sport plane for platform control of interference signals, the platform stabilization loop fuzzy control algorithm, design a stable fuzzy controller circuit, leads to fuzzy control algorithm. Finally, using the above algorithm MATLAB simulation to prove the effectiveness of the algorithm.
