The recent development results of the Actuator Control and Monitoring Unit will be highlighted together with its capability to measure the voltage, temperature and shaft angle of a servo motor along with the angle of the respective control surface. Various test platforms and their applications are described, where the system is currently in use for development and demonstration purposes. Measurement results of different nights are shown and the visible nonlinearities are discussed. Control surface free play and the eifect of the external load on the actuator dynamics is highlighted using measurement data. 收起
