Abstract: Two important directions of research and application in control theory have emerged recently, both of them centered around Dynamic Programming. These are Approximate Dynamic Programming (ADP) and Model Predictive Control (MPC). We argue that while motivated by different concerns, these two methodologies are closely connected, and the mathematical essence of their desirable properties is couched in common ideas of value and policy iteration. In this talk, we explore the connections of several suboptimal control schemes such as certainty equivalent control, open-loop feedback control, rollout, and MPC. Among other things, we show that the most common MPC schemes can be viewed as rollout algorithms or one-step policy iteration methods. Furthermore, we introduce a new unifying suboptimal control framework, based on a concept of restricted or constrained polices, that contains these schemes as special cases.

Abstract: In this Lecture the application of array processing techniques and array communications for enhancing the operation of a wireless sensor network will be presented and the concepts of 'wireless arrays' and 'arrayed wireless sensor networks' (A-WSN) will be introduced. A-WSN is a novel type of wireless sensor networks involving a very large number (hundreds or thousands) of wireless nodes that are randomly distributed in our 3-dimensional (3D) space in unknown locations and are used for monitoring events of interest. When such events occur, nodes will automatically communicate and self organize with their immediate neighbours to form wireless array systems of suitable, although random, geometries and then an ad-hoc wireless network of arrays operating in an infrastructure-less environment. A number of underlying issues under a common framework will be presented such as, node architecture, connectivity rules, communication link requirements (e.g. limited bandwidth, modulation, etc), resolution capabilities (resolving information sources located close together), channel and geometrical uncertainties, etc. These issues will be underpinned by exploiting the knowledge associated with MIMO (multiple-input multiple-output) and MIVO (matrix-input vector-output) wireless architectures in mobile array systems, to wireless sensor network requirements.
