| Abstract | ||
| A mathematical model for calculating the temperature distribution during induction heating of a cylindrical charge has been made. In this model the temperatures of the charge at five nodes are the fundamental variables. A finite element analysis has been made for the melting process of the furnace charge for two materials which are aluminum and iron. This model was used as a reference for the performance of the estimator. A static state estimator with a measurement redundancy of 3.33 for the induction furnace has been developed. Numerical tests show that the static state estimator is satisfactory for the use in state estimation, the weighted least squares WLS approach is an effective technique in estimation, and the criterion proposed in this work is effective for the identification process when bad data exist. | ||
