ABSTRACT:
A direct adaptive fuzzy controller having an adaptation mechanism that modifies the locations of output membership functions to improve performance of the fuzzy controller. The controller has a fuzzy rule base that has a different or unique output membership function for each fuzzy rule. The adaptation mechanism modifies the location of the output membership functions in response to the performance of the controller system, to continuously improve its performance. The controller is a feedback mechanism that functions not only using measured outputs of the process controlled, but has feedforward compensation that causes the controller to anticipate feedback due to measured disturbances or other parameters of the process. The adaptive fuzzy controller can be used for various processes, including combi-boiler domestic hot water temperature control, automobile cruise control, a residential thermostat, duct air temperature or static pressure control for the air handling unit in a heating ventilation and air conditioning system, and furnace temperature control for curing parts.
