Based on the theoretical model of the electrooptical aim platform system,the actual frequency characteristic of the system was identified,and the simulink model of the system,which anastomose with the theoretical model and the actual frequency characteristic,was obtained.According to the demand and application characteristics of the electrooptical aim platform system,the fuzzy + classical complex controller was designed.Classical zeropole assignment controller has the characteristic of high lowfrequency gain and small steady error.Actual application implies that the isolation of the electrooptical aim platform system has reached 1%.The actual precision has arrived at the target demand.Planar fuzzy controller can decrease the overshot,shorten the rise time,and increase the bandwidth.Using intelligent coordinator to switch classical controller and fuzzy controller,the isolation is <1%, and the overshot decreases from 50% to 4%.
