Abstract
A temperature control system incorporating a temperature sensor characterized by thermal inertia which causes the sensed temperature to lag the actual temperature during the transition from one operating temperature for the controlled environment to a different operating temperature. This control system controls temperature as a function of setpoint temperature and the value of a temperature control variable representing the sensed temperature. The value of the temperature control variable is set equal to the temperature sensed by the sensor during steady state operating conditions. In response to a change in setpoint temperature, the system adjusts the value of the temperature control variable to compensate for the thermal lag of the sensor.
