A two-stage synthetic method for accurately realizing the track was presented according to the characteristic of controlled mechanism of two degrees of freedom and mechanical character of controlled driving component. An optimized model of controlled mechanism that can accurately realize the track of many points was built. Using the method of generalized inverse based on windows solves the displacement, velocity and acceleration of compensation movement. Controlled mechanism was simulated and analyzed by using visualization way etc. It provided a reliable and practical work platform for researching and applying controlled mechanism.
