Input allocation with redundant actuators via reduction theorems: some aerospace applications
Abstract: Control design goals are often supported by the action of multiple actuators, differing in size, precision and bandwidth. The combined action of these actuators may then be seen qualitatively as redundant, even though an effective interplay of the available control inputs may induce desirable secondary goals in the closed loop. In this talk we will overview some recently proposed schemes attaining suboptimal allocation via computationally inexpensive gradient-based algorithms. Inspired by a few aerospace applications, we will discuss the impact of the proposed solutions on the arising hierarchy of the design goals. Throughout the talk we will also discuss the impact of stability theory for interconnected systems, notably nonlinear cascades and reduction theorems, to the end of proving desirable stability properties of the feedback control scheme with input allocation.
