posted on 2008-09-15, 13:41 authored by Thomas Steffen, Roger Dixon, Roger M. Goodall, Argyrios C. ZolotasThe High Redundancy Actuator project deals with the construction of an actuator from many redundant
actuation elements. Whilst this promises a high degree of fault tolerance, the high number of components also
poses a unique challenge from a control perspective.
This paper shows how the state space model of a stack of actuation elements in series can be separated into
a high dimensional internal and a low dimensional external subspace. Once the internal states are decoupled
and damped, the behaviour is dominated by the few states of the external subspace. This means that the high
redundancy actuator with many redundant elements behaves just like a conventional single actuator.
