The proper measure of closed-loop performance variation in the presence of modelplant mismatch is discussed in this paper. A generalized closed-loop error transfer function, which is a special representation of the dual Youla parameter and has a close relationship with the pointwise ν -gap metric, is proposed as the suitable means of representing closedloop performance variation in case of plan...

This paper studies the problem of distributionally robust model predictive control (MPC) using total variation distance ambiguity sets. For a discrete-time linear system with additive disturbances, we provide conditional value-at-risk reformulation MPC optimization that is in expected cost and chance constraints. The constraint over-approximated as simpler, tightened reduces computational burde...
