摘要：Abstract: For systems with a great design flexibility regarding the choice of inputs, by designing the actuators themselves, finding a good set of inputs or a good actuator layout, is not trivial. In this contribution, a measure for the correlation and redundancy of inputs to the system based on an Gramian-like output controllability matrix is presented. The input space is orthogonalized with respect to this measure. The main purpose of this input measure is to design new actuators for the system. It can also be used to identify redundant inputs that can be removed. The presented method yields sets of appropriate actuators for the system that give good controllability of the outputs. The method can be applied to large scale linear systems that result from the investigation of FE-models. In this scope, it yields for example the layout of optimal force inputs. The validity of the approach is demonstrated by an illustrative example.
