Original research articleFuzzy PID controller for optoelectronic stabilization platform with two-axis and two-frame

A hybrid fuzzy-PID controller scheme is proposed to maintain line of sight (LOS) stabilize against carriers' disturbances and achieve a higher tracking precision. The control model is established based on two-axis and two-frame utilizing the rotation transformation and Euler equation. Membership functions (MFs) between E and EC of proposed hybrid controller are superior to the ordinary MFs, whether the number of MFs or the types of MFs. Experiments validate that proposed hybrid controller outperforms the conventional PID control scheme.
