摘要
A fuel cell system that employs an on-line self-tuning algorithm that provides temperature control of a fuel cell stack in response to disturbances on the system. The system includes a thermal sub-system having a cooling fluid pump that pumps a cooling fluid through the fuel cell stack, a temperature sensor that measures the temperature of the cooling fluid out of the stack, a radiator that cooling the cooling fluid from the fuel cell stack and a by-pass valve that selectively controls how much of the cooling fluid flows through the radiator or by-passes the radiator. A controller controls the position of the by-pass valve in response to a temperature signal from the temperature sensor. The controller calculates a plurality of variables and a dead-time value, and determines whether the dead-time value should be increased, decreased or kept the same based on an estimate of a dead-time plant model.
