The invention discloses a modeling and simulation method of a tracking mode of an unmanned aerial opto-electronic stabilizing turntable. The opto-electronic stabilizing turntable tracking function is achieved on the base of digital modeling algorithm simulation, and the method is used for three-dimensional virtual simulation training of the unmanned aerial vehicle equipment which carries the opto-electronic stabilizing turntable or theoretic verification of the new opto-electronic stabilizing turntable. The modeling and simulation method mainly includes a functional modeling of the opto-electronic turntable and nonlinear direction line tracking algorithm realization of the opto-electronic turntable. According to the modeling and simulation method, a two-freedom functional model is constructed to realize the nonlinear direction line tracking algorithm. The modeling and simulation method solves the modeling problems of the functional modeling and the tracking algorithm modeling of the opto-electronic turntable of a three-dimensional visual simulation test, and has a good engineering availability.
