Abstract
The conventional thermoresistive sensor-based feedback constant temperature circuits have shown some performance limitations due to the input offset v oltage of the amplifier. The de analysis of this circuit has been presented to graphically demonstrate these limitations. Alternative feedback measure ment scheme without employing the Wheatstone bridge is proposed. PI and pre dictive controller designs are described. Simulation results for these cont rollers and a practical configuration are presented.
