中文摘要	To improve the optoelectronic tracking ability and rope-hanged platform attitude stability, against the interact effect between rope-hanged platform and optoelectronic system during system tracking process, the optoelectronic system fixed on rope hanged platform simplified dynamic model, according to the system's Lagrange dynamic model, was established. Backstepping method was employed to design an integrated controller for both optoelectronic system azimuth direction steering and platform attitude stabilizing. To deal with model's uncertainty and disturbance, a sliding mode controller form based exponential reaching law was adopted to structure the integrated controller. Simulation experiments simulated an optoelectronic system with 600mm caliber telescope, whose inertia fluctuation is 6%. The maximal control moment is 15Nm. And the external disturbance and internal friction effected together. When the line of sight(LOS) azimuth angular input is a step signal with 1rad amplitude, the response's overshoot is 6%, and the response time is 6.2s, and the steady state error is less than 4×10-4rad. When the input is a sinusoidal signal of 0.2rad amplitude with 0.0318Hz frequency, the LOS azimuth angular error amplitude is 5. 6×10-4rad. It is concluded that the controller designed in this article has excellent ability and can ensure the system's stability. © 2012 SPIE.
