Abstract
Expert systems provide a powerful and flexible means for
obtaining the solution to a variety of problems that often cannot be
dealt with by other, more orthodox methods. On the other hand, the
t11eOlYof fuzzy logic provides a mathematical framework to capture
the uncertainty associated with human cognitive processes, such as
thinking and reasoning.
• The problem of collision avoidance is considered. The system
•
•
under consideration is a moving ship to avoid collision with another
moving object and then steer back to reach a certain destination.
The intent of thesis is to use expert and fuzzy approaches to
control the direction of a ship with inertia. In addition, we proposed
a new fuzzy control algorithm to improve the design procedure and
enhance the performance of the controlled system.
Simulation results for the motion of the controIIed ship using
the proposed fuzzy controller showed that it has a superior
performance rather than other controller
