EasyLaser is component-based laser system simulation software,which can be used for laser systems with multioptical paths,multi-wavelength beams and multi-controllers.Beam control system simulation is a main part of EasyLaser.A component framework for beam control simulation is designed,in which optical union transmission of geometry optics and wave optics is the basic part.And kinematic coupling between the rack of system beam director and the inner optical apparatus is also an important part of the simulation framework.A new numerical method is proposed,in which undershoot data and sensor images are updated automatically,and kinematic driver or controller signals are separated automatically.Using the method,the orientation data conversions of rack and many optical mirrors,are executed automatically at every iterative time of the virtual dynamic tracking process.And further optical imaging process and beam controlling process are realized automatically.Therefore the design target for generality,flexibility,and usability of beam control component-based simulation is reached.The tracking and beam controlling can be designed without consideration of the system kinematic composition.In addition,a union beam control example for atmosphere transmission correction is given.It includes tracking tilt mirror and adaptive optics system.Simulation result shows that the low-frequency fluctuation is restrained effectively and the high-frequency fluctuation is corrected obviously.
