The Errors-in-Variables (EIV) setting involves the simultaneous presence of input and measurement noise, and induces nonconvex system identification and control problems. This presentation begins by performing set-membership direct data-driven control in the EIV setting by casting the original nonconvex stabilization problem as an infinite-dimensional linear program (restricting to fixed polyhedral Lyapunov functions). The unknown-but-bounded input and measurement noise terms can be eliminated using robust optimization, resulting in dual variables that are parameterized by the state-space system model. Such a robust decomposition reduces the computational complexity of discretizing the infinite-dimensional linear programs and increases tractability. This method of parameterized robust counterparts is then applied to optimal control problems with input-affine dynamics and semidefinite representable uncertainty. The optimal control problems can be further extended to data-driven safety quantification analysis problems (e.g. estimation of peak values, distances, reachable sets) in the continuous-time and discrete-time settings.
