Claim:
1. A method for controlling a position of an actuator of a positioner system, the actuator being influenced by a restoring force and being driven by an electronically commutated electrical machine comprising: measuring an actual position value of the actuator using a position sensor; generating a position variable based on a predefined set position value and the actual position value using a position controller; generating a phase offset based on an auxiliary signal and the position variable, the generating of the phase offset comprising: controlling a stator arrangement of the electrical machine based on the position variable and the phase offset using a driver circuit, the driver circuit being operably connected to receive the position variable and the phase offset, the driver circuit being configured to (i) allocate the position variable to a space vector, (ii) correct a space phasor angle of the space vector based on the phase offset and (iii) apply a commutation pattern to the electrical machine based on the space vector.
