Control Science Group




Introduction

The behaviors of dynamical systems, which include industrial processes, aircraft, vehicles and even groups of vehicles, are characterized by how these systems evolve under their own physical laws, whether they exhibit some natural equilibria, whether these equilibria are stable, etc. Control science is the study of such behavior through mathematical and numerical analyses, and the design of man-made, feedback laws with the purpose of either improving system stability, or changing the system equilibria so as to safely and efficiently operate at desired operating points. For systems designed to perform specific tasks, such as an aircraft executing a flight path, feedback control is also employed to improve task performance in the presence of outside disturbance, e.g. wind gusts.

 

Programme Overview

The Control Science Group at Temasek Laboratories engages in the analysis and feedback control of dynamical systems in aeronautics and defence. The main types of control systems of interest are autonomous aerial vehicles, unmanned marine vessels and, more generally, multi-agent systems such as squadrons of unmanned vehicles. The programme emphasizes basic research in systems and control theory, as well as development of design methodologies and control algorithms for specific problems, particularly nonlinear and hybrid dynamics, and robust performance. Our major activities comprise: i) development of robust and fault-tolerant flight control designs, including linear and nonlinear fault-tolerant flight controls, efficient nonlinear control allocation, and fault detection and isolation of nonlinear flight dynamics; ii) dynamics modeling and nonlinear control design for planing marine craft; iii) application of control theory in aeronautical design, modeling and analysis. The current focus of the programme is on the formation control and collaborative tasking of multi-agent systems, based on ideas such as hybrid systems, stochastic and heuristic world models, communication topology, and consensus in estimation. The Control Science Group leverages on concurrent research among the control research community both on and off campus. We collaborate closely with the Aeroscience Groups within TL, the Department of Electrical & Computer Engineering in NUS, and the School of Electrical and Electronic Engineering in NTU. Additionally, we conduct joint design studies with our partners in DSO National Laboratories, with the aim of applying and transitioning research results into real systems.
