摘要: In order to improve the ability of rotating turntable resist external disturbance in single-axis rotation modulation inertial navigation system (SRMINS) and ensure smooth running turntable, we designed a dual closed-loop controller. The conventional proportional-integral-derivative (PID) algorithm was employed position loop, tracking differentiator based fuzzy PID proposed used speed realize steady control continuous SRMINS. introduction (TD) guarantees reliability differential signal extraction. Furthermore, combination TD adaptive controller leads motion without overshoot. robustness better stability margin can also be achieved while static error is eliminated performance improved. Simulation results demonstrate that has many merits such as fast response, no overshoot, robustness. It verified regulating parameters real time by rules effectively improves dynamic system, requirement on stable SRMINS satisfied.
