  • Abstract
    The conventional thermoresistive sensor-based feedback constant temperature circuit have shown some performance limitations due to the input offset voltage of the amplifier. The d.c. analysis of this circuit has been presented to graphically demonstrate these limitations. Alternative feedback measurement scheme without employing the Wheatstone bridge is proposed. PI and predictive controller designs are described. Simulation results for these controllers and a practical configuration are presented
