"Plans are worthless, but planning is everything."
— Dwight Eisenhower

Uncertainty is the key reason for going from feedforward to feedback control. Yet, even very sophisticated modern control strategies such as MPC have to deal with uncertainty surrounding models, forecasts of exogenous signals (renewable generation, energy demand, and market prices). In principle one can distinguish two main approaches towards control and optimization under uncertainty:

  • Worst-case considerations, which tend to be conservative
  • Stochastic approaches, which require extra modelling efforts.

In this context, we work on stochastic optimization and control of nonlinear systems. Recent outcomes comprise toolboxes and new methods.
