Fuzzy weighting technique is carried out and applied to motion control of an amphibious hovercraft to resolve the motion control problem with navigation characteristic change greatly. Multiple models are constituted to cover the navigation characteristic variety bring by ship speed change. Controllers are designed for every speed point respectively, and fuzzy rules figure out controller weight to...
The maneuverability of an Air Cushion Vehicle (ACV) is mostly different from a conventional surface ship, so its course-keeping problems based on switching control were studied. The fuzzy PID control and multiple model control method based on fuzzy switching are respectively applied to the course-keeping of air cushion vehicle, and simulation experiments are conducted. The experimental results show...
The basic model for computing resistance of air cushion craft bow skirt is established, simulations are carried out in finite element analysis software ANSYSCFX to compute the coefficient of bow skirt resistance. According to the results, the law of the effect of skirt finger inclination angle on skirt resistance coefficient is showed, and which provides a reference for hovercraft hull design.
This paper proposes an adaptive data fusion algorithm for a multi-rate sensor system based on incomplete measurement. The algorithm has built a method of sensor subsystem fault detection. The subsystem failure is detected and the incomplete measurement is confirmed to avoid contaminating the entire system due to the single failure. The algorithm has built the subsystem switch control and it also introduced...
