Nowadays, a multitude of flight control computers and sensor systems are available to support research activities related to testing various unmanned aircraft systems. Either for initial flight testing of a newly designed aircraft or for retrofit purposes, most flight control computers offer a wide variety of functionalities, with a clear exception of servo actuators of flight control systems. Due to similarities in underlying operating principles, paired with the knowledge and expertise gained with monitoring and control, functionalities can be reused in Electro-Mechanical Actuators (EMA) dedicated for bigger UAVs and transport aircraft. Due to size restrictions, merely Commercially Off-The-Shelf (COTS) servos can be chosen for present research UAVs. These COTS servos lack desired functionalities, like power consumption or position monitoring. Having the ability to record such data would be beneficial for research purposes. Moreover, there is no commercially off-the-shelf servo actuator for small to medium-sized UAVs, which would allow high configurability on feedback and closed-loop control capability. The present work addresses this problem by introducing a novel actuator control and monitor unit. Detailed design considerations and goals will be introduced along with the state of the development. For validation of the functionalities and usability of the system, laboratory and field test results will be shown.
