Linear-Convex Optimal Steady-State Control

We consider the problem of designing a feedback controller for multivariable linear time-invariant system, which regulates system output to solution an equality-constrained convex optimization despite unknown constant exogenous disturbances; we term this linear-convex optimal steady-state (OSS) control problem. introduce notion optimality model, and show that existence model is sufficient reduce OSS stabilization This yields design framework unifies extends existing methods in literature. illustrate approach via application frequency power networks, where our methodology recovers centralized distributed controllers reported recent
