Abstract: This paper presents a model of the azimuth and altitude of dish solar condenser by the research on the dish solar thermal power tracking execution system. The system builds a dynamic model of electromechanical coupling using matlab / Simulink tools. The modeling method has a good tracking ability through simulating analyzing of the dynamic response characteristics. This article studies the moment of inertia influence on tracking accuracy by analyzing the relationship between the load moment of inertia and the angular velocity and angular acceleration of tracking system. This model provides a theoretical basis of hardware design.

Key words: dish Solar, tracking system, response feature, modeling
