AN ADAPTIVE FUZZY CONTROLLER AND SIMULATION METHOD

摘要

An adaptive fuzzy controller for use with a controlled system and for controlling a first object of the controlled system in accordance with a system control parameter is described; whereby the fuzzy controller comprises: a fuzzy rule base including control rules for performing a fuzzy inference operation; and an adaptive unit for adaptively changing a parameter relating to one of the control rules of the fuzzy controller in accordance with a multi-dimensional performance table having at least three dimensions, the inputs for the table being an error in the system control parameter, the rate of the change of the error in the system control parameter and a value related to a state of the controlled system or a value related to a state of an object in the controlled system. Also methods of operating the controller are described, in particular its use in a control system for a nuclear reactor. A simulator is described for testing the controller.
