Embodiment Construction
[0045] Such as figure 1 As shown, the system includes anti-roll controller, fin angle / wing fin angle intelligent optimizer, two sets of fin / wing fin electric servo systems, reference model, roll angle detection device and state estimator, etc., among which the anti-roll control The controller is composed of three parts: feedback linear controller, fuzzy tree-based adaptive controller and error observer.
[0046] Step 1: The roll detection device detects the roll angle, and estimates the roll angle and roll angular velocity of the system through the state estimator, and sends the difference with the given value to the feedback linearization controller;
[0047] Step 2: When the system is uncertain and qualitative, the feedback linearization controller has a large error, and the output of the feedback linearization controller is corrected by the adaptive controller based on the fuzzy tree to obtain the required roll righting moment; after correction The output signal of the ant...
