ABSTRACT:
Controlling an orienting/positioning system having a sensor and actuator for controlling at least one of an orienting and positioning action of the sensor. The invention (1) evaluates pre-action output information of a sensor in order to detect the position of a pattern in the input space of the sensor, (2) determines a targeted post-action position of the pattern in the input space of the sensor, (3) defines an actuator command by mapping any deviation of the pre-action and post action position in the input space to actuator control coordinates using a predefined mapping function, (4) controls the actuators according to the defined command to execute the orienting/positioning action, (5) detects the real post-action position of the pattern in an input space of the sensor, (6) adapts the mapping function based on differences between the real post-action position and the targeted post-action position of the pattern in the input space.
