Robust fuzzy control based on disturbance observer in fight simulation turntable

A robust fuzzy control method based on disturbance observer is put forward for DCS simulation turntable system, employing the frequency characteristic to design filters and analysing the functions and effects of filters comparatively. Experiments and trials show that under the external disturbance and parameter perturbation, such method can guarantee the high accuracy, stability and excellent tracing property of flight simulation turntable system.
