Abstract:
1. A correction method for processor-controlled digital regulation of a drive motor, comprising the steps of: from a circuit consisting of an encoder and a timer, producing a measurement series, consisting of a plurality of individual measurement values representing an operational characteristic of a drive motor; in a processor, monitoring successive measurement series obtained from said circuit to identify any individual measurement values therein that exhibit a sudden, non-gradual change of a real value thereof from individual measurement value-to-individual measurement value in the measurement series being monitored; in said processor, sorting out from said measurement series any of said measurement values therein exhibiting said sudden, non-gradual change; and in said microprocessor, generating an at least partially corrected measurement value and replacing the sorted out measurement value in the measurement series with said at least partially corrected measurement value.
