HRA - Intrinsically fault tolerant actuation through high redundancy
conference contribution

tolerant actuators for high-integrity and/or safety-critical applications. The High Redundancy Actuator
(HRA) project aims to exploit a large number of very small actuation elements to make up a single large
actuator. This is in contrast to current technology where a relatively low level of functional redundancy is
used. The HRA elements are configured and controlled in such a way that faults in individual elements are
inherently accommodated without resulting in a failure of the complete actuation system. The HRA project
research challenges are outlined and progress to-date is discussed.
