Modeling and simulation of strapdown 3-axis stable and tracking platform

摘要

Strapdown 3-axes stable and tracking system is used to make detector mounted on the moving vehicle aim and track the moving objective. This paper builds up the kinematics model and dynamic model of the system, brings forward a kind of hybrid Fuzzy-PID control algorithm. We make full use of the advantages of each of them in order to enable the system to have better stability and tracking ability in the case of largely varied load torque. This algorithm has the advantages of simpleness, swiftness and can be easily completed.
