Abstract
A method for controlling a fuel cell hybrid electric vehicle (FCHEV) with sensor fault tolerance includes receiving current measurements of a fuel cell, a battery, an ultracapacitor, and a voltage measurement of a DC-bus from sensors; detecting and estimating a sensor fault in at least one of the current measurements using a radial basis function neural network (RBFNN); calculating a new value for a single parameter of the RBFNN according to a minimum learning parameter scheme; calculating a duty cycle value for each power converter; and applying the calculated duty cycle value to power converters that connect the fuel cell, the battery, and the ultracapacitor to the DC-bus, to maintain a current distribution despite the sensor fault.
