[0049] The present invention will be further described in detail below in conjunction with the drawings.
[0050] The present invention is based on a fuzzy adaptive observer-based under-driven surface craft trajectory tracking control system, such as figure 1 Shown:
[0051] 1) The under-actuated surface craft trajectory tracking control system based on fuzzy adaptive observer of the present invention includes sensor system 6, fuzzy adaptive observer system 7, fuzzy logic adaptive system 9, observer error gainer 12, and Riccati-like equation solution 器17, controller 18, guidance system 23. The sensor system 6 includes position and heading sensors. The sensor system collects ship position and heading information, and at the same time transmits it to the observer error gainer 12 together with the position and heading state estimates output by the observer and the high-frequency disturbance estimates. . The fuzzy adaptive observer system 7 includes an observer module 8, a fuzzy logic...
