Paper Abstract

Two-axis optoelectronic tracking equipments generally use such mode that azimuth and pitch system are independently controlled. It leads to the two structures completely uncoupled, and reduces the state space dimension. But the main problem is that the rotational inertia of azimuth is much larger than that of pitch, which leads its dynamic tracking performance is worse. So to find a more suitable mechanics and more effective control strategy is necessary. Considering the tracking ability, this paper designs BMC (bandwidth mutual compensation) to uniformly correct the error of both the azimuth and pitch system in real time, it is realized by cross coupling control to the azimuth and pitch. The simulation result verified that compared with classical uncoupling system BMS not only guarantees the state space dimension but improves systematic tracking performance about 2" therefore, it is an effective control mode to the two-axis photoelectric tracking equipments.
