Stochastic Control-A Moment Approach to Sparse Control Design
July 2016
Proceedings of the 22nd International Symposium on Mathematical Theory of Networks and Systems
We consider design of sparse controllers for a stochastic linear system with infinite horizon quadratic objective. We formulate the non-sparse optimal solution through a semidefinite program for the second order moments of the states and inputs. Given that the centralized non-sparse controller solves a linear equation in these moments, we find sparse least squares approximate solutions to this linear equation. The performance of the approach is shown with several simulations.
