This letter considers the optimization landscape of linear dynamic output feedback control withrobustness constraints. We consider the feasible set of all the stabilizing full-order dynamical controllers that satisfy an additionalrobustness constraint. We show that this-constrained set has at most two path-connected components that are diffeomorphic under a mapping defined by a similarity transformation. Our proof technique utilizes a classical change of variables incontrol to establish a surjective mapping from a set with a convex projection to the-constrained set. This proof idea can also be used to establish the same topological properties of strict sublevel sets of linear quadratic Gaussian (LQG) control and optimalcontrol. Our results bring positive news for gradient-based policy search on robust control problems.
