• W2104790145 abstract "This work addresses the problem of tracking constant references for linear systems subject to control saturation. The main idea is to present LMI conditions in order to design both a stabilizing controller and an anti-windup gain. These conditions ensure that the trajectories of the closed-loop system are bounded by an invariant ellipsoidal set, provided that the initial conditions are taken in this set and the references and the disturbances belong to a certain admissible set. The constant reference tracking and constant disturbance rejection is taken into account by the internal model principle, i. e., considering the introduction of an integral action in a unitary output feedback scheme. We also introduce the error co-ordinate representation, where is proved that there exists only one equilibrium point inside the linearity region and that this equilibrium point ensures perfect reference tracking. In order to consider the saturation effects, we use a modified sector condition, introducing new degrees of freedom to the synthesis problem. In a first step, the proposed framework was applied to the control scheme called “intelligent integrators”, regarding continuous-time systems. However, this control scheme does not allow the simultaneous synthesis so it is simplified to the so called “classical” anti-windup scheme. Based on this simplified control structure, LMI conditions are directly derived, avoiding therefore the necessity of applying iterative schemes. Convex optimization problems aiming at the maximization of the invariant set of admissible states and/or the maximization of the set of admissible references/disturbances are proposed. We show, by means of an example, that the obtained results are less conservative than the ones previously presented in related works. In these examples, we also show that a study about the existence of other equilibria inside the invariant set is worthwhile. Later, the proposed framework is extended to discrete-time systems, where new LMI conditions are presented in order to synthesize the controller and present an estimate of the stability domains. Due to a lack of related works, our framework is applied to stable, unstable and integrator examples. These examples consider both single and multi-variable systems. Finally, we conclude this work with a study about the possibility of existence of other equilibria inside the invariant set. For the single-input case, we show that this is only possible if the open-loop system is asymptotically stable. In this case, in order to avoid convergence to these points, additional constraints on the admissible references to be tracked should be considered. It is worth to emphasize that such kind of analysis has not been performed in previous works." @default.
