Research on modeling and simulation for pitch/roll two-axis strapdown stabilization platform

Large tracking field of view, low-cost, large angular velocity, compact structure and miniaturization design are the requirements of missile seeker. To meet the requirement of the missile seeker, the pitch/roll two-axis strapdown stabilization platform is investigated. Complete kinematics and dynamics models of the pitch/roll two-axis strap-down stabilization platform are built. At the same time, on the basis of the platform structure and the working principle of DC torque motors, the mathematical model of DC motor is built. At last, the stabilization and tracking principle of the pitch/roll seeker are researched. Simulation and analysis results show that the models and analysis of the pitch/roll two-axis strapdown stabilization platform proposed in this paper are correct, which have some actual engineering value and provide some references for the further research on the pitch/roll two-axis stabilization platform.
