We develop tools and algorithms for the scalable analysis of nonlinear system descriptions and the design of control laws using computational tools based on the Sum of Squares decomposition and Semidefinite Programming. In particular, our group concentrates on:
+
== [http://sysos.eng.ox.ac.uk/wiki/index.php/Research Research Areas] ==
  
* Nonlinear systems analysis, Sum of Squares optimization and Lyapunov techniques. In this spirit, we have developed methods for stability analysis of systems described by Ordinary, Delay and Partial Differential Equations, with applications in Systems Biology, Population Dynamics and Engineering.  
+
* Nonlinear systems analysis, Sum of Squares optimization and Lyapunov techniques.  
 +
* Systems and Synthetic Biology.
 +
* Software Development.
 +
* Large-scale Networked Systems analysis with communication and structural constraints.
 +
* Fluid mechanics and Heat transfer, from a control perspective.
 +
* Complexity reduction of networked systems.
 +
* Scaling Sum of Squares and Semidefinite Programming.
 +
* Robust analysis and design of (deep) neural network controllers.  
 +
<br>
  
* Software Development (SOSTOOLS). This can be found [http://www.cds.caltech.edu/sostools here]. A new version is currently under development and more examples will be added soon.
+
[http://sysos.eng.ox.ac.uk/wiki/index.php/Research Click here] for a more detailed description of these research areas.
  
* Large-scale Networked Systems analysis with communication and structural constraints. Examples in this field come from synchronization phenomena in oscillator Networks with applications to Kuramoto couplings and synchronization of cardiac cells and Network Congestion Control for the Internet. We are looking at multi-agent systems consensus under communication and structural constraints such as the effect of time delays and switching topologies.
