Abstract :
With the effect of ocean wave, the motion of wave-measured radar has a periodic swing and high-frequency dither, which makes radar images have a serious polluted noise. In order to enhance the quality of radar images and realize the high stability of wave-measured radar´s attitude, the method of fuzzy-PID with repetitive control compensation (FPRCC) is designed. This method has synthesized some merits with fuzzy-PID and RCC, which has characters of high-robust and independent of mathematical model from fuzzy-PID, the characters of RCC is used to reduce the high frequency oscillation error of wave-measured radar´s attitude. From the simulation result, the conclusion is showed that the capability of fuzzy-PID with RCC is superior to fuzzy-PID, which can wipe off the sudden change of attitude movement, and realize the high-precision attitude control of wave-measured radar.
