摘要	A conformal infrared optical seeker was designed to compensate its angle increment nonlinear errors. The reasons to generate the nonlinearity of focal length and nonlinearity of deviation were analyzed, the effect of these nonlinearities on the seeker control system was discussed and a feedforward compensation method for the nonlinearity was given. On the basis of conformal optics characteristics, the principles of nonlinear errors of focal length and deviation were present in detail by data and charts. Then, according to the angle increment algorithm in a seeker control system, the effect of nonlinearity of conformal infrared seeker on the tracking error was analyzed and a feedforward compensator based on an angle increment nonlinear model was proposed for the correcting angle increment error. Finally, simulation work was performed to get the tracking error in the compensated seeker control system. Experimental results show when the focal length of the conformal optical system varies from 90 mm to 91.125 mm and its deviation varies from 0 to 1.109, the tracking error can be controlled under 0.038, which meets the requirement of conformal optical seeker for the precision of nonlinear tracking error less than 0.1.
