Electromagnetic torque unit regulation process for polyphase rotating electrical machine e.g. rolling mill driving rotor, involves determining harmonic values of current and/or voltage generated by inverter to set instantaneous torque

摘要

The process involves controlling switching according to the setting of an instantaneous torque attained in a subsequent regulation instant. Harmonic values of current and/or voltage generated by an inverter are determined. The values are used for setting the instantaneous torque to limit difference between average of instantaneous torques between two successive regulation instants and the set electromagnetic torque unit. Independent claims are also included for the following: (1) an information recording medium storing instructions for executing a process of electromagnetic torque unit regulation (2) a data structure stored in a memory to allow the regulation of an electromagnetic torque unit (3) an electromagnetic torque unit regulation unit.
