Mathematics and Statistics Colloquium : Penalizing control volatility in nonlinear optimal control Other events...
Abstract: Change is necessary in any dynamic environment, but there is always a cost incurred when implementing change; one of the most obvious is wear and tear on the physical components in a system. In the optimal control field, the cost of change is almost always ignored, and this can lead to “optimal” control strategies that are volatile and impractical to implement. This talk will introduce a class of non-smooth optimal control problems in which the cost of change is incorporated via an objective term that penalizes the total variation of the control signal. We describe a discretization method, based on nonlinear programming and a novel transformation scheme, for converting this class of problems into a sequence of smooth approximate problems, each of which can be solved efficiently. Convergence results for this discretization scheme are discussed. The talk will conclude with examples in fisheries and crane control.
