For a typical mechatronic system, the mechanical system and control system is designed in serial, which makes it difficult to design the mechatronic system efficiently and perfectly. In order to foresee the final control performance of the two-axis Fast Steering Mirror system (FSMs), Mechanical-Control Co-simulation Method is presented in this paper. The Mechanical-Control Co-simulation Method is taken by the Adams and Matlab software together. Firstly, the dynamic model of FSMs mechanical system is built in Adams exactly. Secondly, Mechanical-control Co-analyzing Model is set up in Matlab/simulink environment with Adams/control interface toolbox. Thirdly, parameters of the mechanical system are identified and the controller is designed, and then, the open-loop and close-loop control performance is studied in detail. FSMs is machined and assembled, and the open-loop and close-loop performance is tested to validate the accuracy of the Mechanical-Control Co-simulation Method. Experimental results show that the difference of resonance frequency between the simulation model and experiment model is less than 5%, and the difference of bandwidth between the designed and the tested is less than 15%. These omissions in no way impacted the general validity of the work or concept presented in this thesis.
