Its entitative simulation models were categorized into scene model,target imaging model, prediction model and tracking control model, etc. Easy Laser was general component simulation software. Based on friendly modeling method for used and program auto growing technology of Easy Laser, 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.
