Double-Loop Temperature Control of an On-Off Heating System

This thesis proposes a double-loop on-off temperature control which comprises two loops of compensation. The configuration is simple and the stability and performance can be easily achieved with proper choice of two parameters in the controller. For the performance, the controller switches the current through the heater in order to achieve the goal of power efficiency and temperature regulation; switching noise suppression and small regulation error can be achieved at the same time.
The proposed control scheme is applied to a water heater. The experimental results reveal that the regulable range of temperature is from room temperature to 100 ¢J¡]room temperature ¡Ù 30 ¢J¡^, with temperature regulation error within ¡Ó1 ¢J. It conforms the stability and accuracy of the proposed control scheme.
