Research on Co-simulation Method in ADAMS and MATLAB for Missile Seeker’s Stabilization Platform Design

Missile seeker’s stabilization platform, also called coordinator was one of the key parts of seeker. In this study, an ADAMS/Matlab co-simulation environment for the design of seeker’s stabilization platform was proposed. First, the mechanical model of coordinator is analyzed, virtual prototype model of the coordinator was built through SolidWorks and ADAMS, and the control model of the coordinator was built through MATLAB and Simulink toolbox. Then co-simulation model was achieved through ADAMS/Control block and Matlab/Simulink port. At last, model accuracy was verified by using coordinator’s real data. With all of these, control system of the coordinator was designed in the co-simulation environment, and isolation performance of the coordinator was tested in this co-simulations environment. Simulation results show that the coordinator’s design work based on the ADAMS/Matlab co-simulation environment is feasible, effective and practical, and it has advantages such as higher fidelity of controlled objective, easier for modeling and debugging compared with traditional design strategy of mathematical methods, and provided a new design approach for high performance coordinator.
