A method for detecting and dynamically updating an end stop position of a slide-out assembly comprises the steps of: synchronizing a movement of each of at least two slide-out actuators during an extension operation; detecting a decreased speed of each slide-out actuator of the said at least two slide-out actuators; stopping each of the at least two slide-out actuators when the speed reaches an end-stop position threshold; comparing a travel distance of the at least two slide-out actuators to the said last saved travel distance; and updating the said last saved travel distance to a new saved travel distance, if the travel distance is greater than or less than the last saved travel distance. A control system for detecting and dynamically updating the end stop position is also provided.

A piezoelectric positioning device (1) has at least one piezoelectric actuator (3) having a first connection contact (4) and a second connection contact (5). A control device (6) with digital/analog converters (12, 16) connected to the connection contacts (4, 5) is used to control the at least one piezoelectric actuator (3). In comparison with a coarse converter (12), a fine converter (16) has a comparatively smaller voltage range and lower voltage levels, with the result that a high degree of positioning accuracy can be achieved.

A motor controller receiving as input an encoder signal changing in response to a driving position of a motor, outputting a motor driving command in response to the encoder signal to control at least one of the driving position or a driving velocity of the motor, includes an interrupt processing section to execute interrupt operations every prescribed interrupt cycle, a low-frequency processing section to selectively execute a subset of the interrupt operations every prescribed number of the interrupt cycles, and a high-frequency processing section to execute another subset of the interrupt operations every prescribed interrupt cycle, wherein the high-frequency processing section executes at least an operation to detect the driving position indicated by the encoder signal, wherein the low-frequency processing section executes at least an operation to generate the motor driving command.
