✦ Synopsis

Output feedback controllers for disturbance attenuation of linear systems with constraints on inputs are studied. The constraints are limited actuator capacity as well as limits on the actuator rates. The main features include guaranteed performance levels that depend on both actuator magnitude and rate limits, and controllers that operate at, or close to, maximum actuator capacity. The controllers have a structure similar to those used in the linear parameter varying (LPV) approach. Su$cient conditions for "nding appropriate nonlinear control laws are expressed in terms of a convex search.

We consider the problem of regulating the state of a linear system within a prescribed region of the state-space in the presence of disturbances and control saturations. While prior work has focused on full state-feedback, we consider the case of noisy output feedback. For the scalar control case, w
