| Abstract: | A thermostatic control system of oil cup with single-chip computer as its heart is presented to used in insulating oil dielectric loss measuring system in the paper. A subdivision controlled integral-separated PID algorithm is proposed to control the induction heating circuit and a high accuracy temperature measuring circuit with nonlinear temperature calibration is detailed The proposed system can obtain more quickly dynamic process and less steady-state deviation over conventional electric cooker mode. Its measuring principle,system structure , and the algorithm concerned are analyzed. The experimental measurements are used to verify the theoretical prediction and analytical discussion. |
