Abstract
A method is for compensating for a rotor angle deviation of a motor, which may be used as an actuator, e.g., as a servo actuator, in a steering system. The rotor angle deviation is compensated for by a piecewise linearized control of the difference between a desired rotor angle, which is based on a manual torque and a stored rotor angle, and a measured rotor angle, a control factor of the control being variable as a function of the control range.
Claims19
A method for compensating for a rotor angle deviation of a motor, comprising:
- piecewise linearized controlling of a difference between a desired rotor angle and a measured rotor angle, the desired rotor angle being based on a manual torque on a steering handle and a stored rotor angle, a control factor of the controlling being variable as a function of a control range.
A steering system, comprising:
- a device adapted to perform piecewise linearized controlling of a difference between a desired rotor angle and a measured rotor angle, the desired rotor angle being based on a manual torque on a steering handle and a stored rotor angle, a control factor of the controlling being variable as a function of a control range.
