Global regulation of input-saturated ANCBI linear systems subject to persistent disturbances∗
نویسندگان
چکیده
A control strategy is described for globally stabilizing ANCBI linear plants subject to input constraints in the presence of persistent arbitrarily large but bounded disturbances. Unlike the disturbance-free case, the presence of persistent disturbances imposes critical structural conditions on the disturbance-to-state map of the system in order to achieve global internal asymptotic and global external BIBO finitegain stability. The proposed technique is based on a weaker concept of robust positive invariance, referred to as positive quasi d-invariance, which allows the achievement of global results more directly than other concepts of robust positive invariance.

Control of Uncertain Systems under Constraints: Switching Horizon Predictive Control of Persistently Disturb ed Input-Saturated Plants
In order to provide computationally affordable predictive control algorithms, predictive switching logic schemes are considered whereby a feedback-gain is switched-on at any time from a family of candidate feedback-gains so as to control a discrete-time input-saturated LTI system possibly subject to persistent bounded disturbances of unknown arbitrary magnitude. It is constructively shown that ...

where xðtÞ 2 R uðtÞ 2 U R, 8t 0 wðtÞ 2 V R, 8t 0 the aim is to find a state feedback function g :R ! R such that there exists a compact set containing the origin in its interior, which is globally attractive for all state trajectories of the closed loop system with u(t)1⁄4 g(x(t)). The trajectories have to ultimately enter this set without constraints violation. This problem can be reformulated...
متن کاملPredictive PI-control of linear plants under positional and incremental input saturations
A predictive control strategy is developed for set-point tracking of LTI plants in the presence of joint positional and incremental (rate) input saturation constraints. The resulting control algorithm is built so as to provide an integral action capable to asymptotically reject arbitrary constant disturbances. This task is achieved by possibly modifying on-line the set-point in the case this be...
متن کاملModel-Based Predictive Control
MBPC is a feedback-control methodology suitable to enforce efficiently hard constraints on the variables of the controlled system. It is shown that the method hinges upon a constrained open-loop optimal control problem along with the adoption of the so-called receding-horizon control strategy. In the important case of time-invariant linear saturated ANCBI systems, MBPC algorithms can be devised...

This paper proposes a hybrid control scheme for the synchronization of two chaotic Duffing oscillator system, subject to uncertainties and external disturbances. The novelty of this scheme is that the Linear Quadratic Regulation (LQR) control, Sliding Mode (SM) control and Gaussian Radial basis Function Neural Network (GRBFNN) control are combined to chaos synchronization with respect to extern...
