Relationships Between Affine Feedback Policies for Robust Control with Constraints

Proc. 16th IFAC World Congress on Automatic Control, July 2005Abstract
This paper is concerned with the analysis of a recently-proposed
robust control policy for linear discrete-time systems subject to
bounded state disturbances with mixed constraints on the states and
inputs, which parameterizes the input as an affine function of the
past disturbance sequence. The paper shows that this disturbance
feedback policy is equivalent to the class of affine state feedback
policies with memory of prior states, and thus subsumes the
well-known classes of open-loop and pre-stabilising control
policies. Furthermore, the parameterization transforms the
non-convex problem of finding an admissible state feedback policy to
an equivalent and tractable convex problem.
