METHOD AND APPARATUS FOR ADAPTING COMMUTATION FOR AN ELECTRONICALLY COMMUTATED ELECTRICAL MACHINE

摘要

A method for controlling a position of an actuating element, to which a restoring force is applied, in an actuator system having an electronically commutated electrical machine, includes controlling the position of the actuating element as a function of a predefined setpoint position specification and an actual position specification. A position control unit provides an actuating variable which is associated with a space vector with which a stator arrangement of the electrical machine can be driven. The method further includes applying a correction variable to the space vector in order to correct a space vector angle of the space vector; providing an auxiliary signal; varying the space vector angle of the space vector, which is defined by the actuating variable, by the auxiliary signal; and integrating a variable to give an integration value.
