Motor control system for adaptive current profile

摘要

A control system is provided for a multiphase motor having a plurality of stator phase components, each stator phase component comprising a phase winding formed on a core element, and a rotor. A plurality of motor control schemes are stored in memory or calculated dynamically during motor operation. Subject to user or system selection, one of the motor control schemes is selected by a controller for implementation. The controller generates control signals that are applied to energization circuitry for supplying current to the phase windings with a particular current waveform profile in accordance with the selected motor control scheme. The controller has an input terminal for receiving a user initiated torque command signal representing a desired motor torque. Each motor control scheme provides motor driving current that corresponds to torque command signals received at the controller input terminal. In an automatic mode, the controller accesses the appropriate control scheme to meet the torque tracking requirements of the system.
