TEMPERATURE CONTROL METHOD OF A GLOW PLUG, ENABLING TEMPERATURE TO BE RAPIDLY CONTROLLED BOTH IN CASE OF INTERFERENCE AND IN CASE OF NON-INTERFERENCE

摘要

PURPOSE: A temperature control method of a glow plug is provided to enable the interference in the temperature of the plug to be quickly corrected.;CONSTITUTION: A temperature control method of a glow plug comprises the next steps. A mathematic model(4) calculates an output variable(X) from an input variable and supplies the output variable and thus the expectation resistance(R_e) of an electric variable is calculated. The electric variable is measured and determined. A first error signal(e_1(t)) is generated by the calculated expectation resistance. On the value calculated from the value of an effective voltage(U_eff) and the first error signal used as the input variable of the mathematical model, the model calculates the output variable, which represents the expectation resistance of the electric variable, from the input variable. The output variable of the mathematical model is used for calculating the corrected value for the effective voltage. The effective voltage is changed to the corrected value.;COPYRIGHT KIPO 2011
