Some issues in the control of distributed/stochastic systems
I will discuss recent results in two directions. The first involves control in distributed, pattern forming systems with finely resolved sensing and actuation. There will be extensive experimental results from catalytic reactions on laser microaddressable catalyst surfaces. Supporting modeling/computations will also be presented. The second direction involves what we call "coarse control" of atomistic systems. An "equation-free" methodology for performing controller design computations directly based on microscopic/stochastic simulators will be presented. This approach sidesteps the necessity of obtaining macroscopic governing equations in closed form.
