Course keeping of an Air Cushion Vehicle based on switching control

摘要

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 that the fuzzy PID control with dual-mode switching has a good dynamic performance and steady-state performance, but the control variable should jump when switching occur, there is its shortcoming. The multi-model control method based on fuzzy switching control not only can achieve a good course-keeping effect, but also there no variable jump, it is a good control method for air cushion vehicle course keeping.
