Simulation of compound-axis tracking systems based on EasyLaser

Compound-axis servo system is effective on the improvement of tracking stability and precision for optical beam pointing system. Its entitative simulation models were categorized into scene model, target imaging model, prediction model and tracking control model, etc. EasyLaser was general component simulation software. Based on friendly modeling method for used and program auto growing technology of EasyLaser, component-based compound axis tracking system simulation method was proposed. The Simulink circumstance nest mode based on Matlab engine was discussed and simulation creditability was proved. Furthermore, amalgamation of kinematics, control, optical propagation was partially analyzed, some assistant components were proposed. Through numerical solving method, control driver decoupling procedure was simulated automatically. Component simulation problem for compound-axis system with structure and optical layout multiplicity was solved at all. Simulation example of compound-axis joint with adaptive optics system illustrates that the component simulation method has the capacity of retaining simulative creditability and enhancing the simulative facility and adaptability.
