Taking the filling-demagnetization device for workpiece of grinder as a research object,the self-adaptive filling-demagnetization device is designed based on BF531 DSP.The on-line identification for excitation coil param-eter of electromagnetic chuck is carried out by using system identification method.Based on the identification result, the interval which the reverse -bias voltages apply on the excitation coil of electromagnetic chuck is self-adjusted. The demagnetization effectiveness and efficiency of filling-demagnetization controller are verified by experiment.
