Summary

 

Summary

My particular area of expertise in the design of efficient numerical methods and embedded computing architectures for solving advanced optimal control and estimation problems in real-time. Central to my work is the development of theory and methods for model predictive control (MPC) to handle nonlinearities and uncertainties in a systematic fashion. I am also interested in developing new multi-objective optimization methods for the design of cyber-physical systems, where physical systems affect computations and vice versa in a closed loop; by incorporating computational components into a system, one can engineer functionalities that are impossible by physical design alone. I am particularly interested in exploring how the complexities of the algorithms, computing architecture and physical realization need to be traded off to satisfy given system-wide performance specifications.

I have a joint appointment in the Department of Electrical & Electronic Engineering and the Department of Aeronautics. My theoretical research is therefore motivated by a wide variety of problems in the design of aerospace, renewable energy and information systems. Applications include scheduling of computation and communication in aerial and mobile robotic networks, skin friction drag reduction over aerofoils, gust and load alleviation in wind turbine blades and control of satellites.

See my Google Scholar page for my most recent publications and preprints.

PHD STUDENTSHIPS AVAILABLE

If you are interested in doing a PhD under my supervision in the general area of model predictive control and optimization, please contact me with your CV, transcript of academic records and a personal statement. We have a number of open studentships available that can be tailored to areas of mutual interest. I am particularly looking for an outstanding student interested in a project that is in collaboration with Mathworks, the creators of Matlab and Simulink. 

Software

ICLOCS: Solves nonlinear optimal control problems subject to constraints.

SPLITC code generation for Model Predictive Control based on operator splitting methods. SPLIT is capable of generating both software and hardware-oriented C code to allow quick prototyping of optimization algorithms on conventional CPUs and field-programmable gate arrays (FPGAs). See our paper for more details.

protoip: Quickly prototype C-based IP in FPGA hardware. This tool abstracts many specific low-level FPGA design details and shifts the main focus to algorithm coding and boosts productivity.

Media

ECC 2016 Tutorial Session on Embedded Optimization: Presentations can be downloaded here.

My talk on co-design of optimization-based controllers, given at MATLAB EXPO 2015, is now available.

My talk on cyber-physical systems, hosted by the IET, is now available (audio starts at 1:05). See also the companion talk by Andy Chang from National Instruments with a further Q&A from both of us.
