—This paper considers closed-loop quadratic stability and 2 performance properties of linear control systems subject to input saturation. More specifically, these properties are examined within the context of the popular linear antiwindup augmentation paradigm. Linear antiwindup augmentation refers to designing a linear filter to augment a linear control(More)
—This paper treats the problem of synthesizing anti-windup compensators that are able to handle plant uncertainty in addition to controller saturation. The uncertainty considered is of the frequency-weighted additive type, often encountered in linear robust control theory, and representative of a wide variety of uncertainty encountered in practice. The main(More)
This paper presents a conditioning scheme for a linear control system which is enhanced by a neural network (NN) controller and subjected to a control signal amplitude limit. The NN controller improves the performance of the linear control system by directly estimating an actuator-matched, unmodeled, nonlinear disturbance, in closed-loop, and compensating(More)
The aim of this paper is to give a novel solution to the full order anti-windup (AW) compensation problem. The main contribution of the procedure proposed is the reduction of the LMI optimisation problem that has generally been solved, to that of solving a single Riccati equation. This yields a bounded-real Riccati equation where the best performance is(More)
