Robust Output Regulation of Disturbed Systems with Uncertainties and Input Constraints

Robust Output Regulation of Linear Systems with Structural Uncertainties

In this paper, we study the problem of robust regulation for a class of linear uncertain systems which admit the so-called Recursive Augmentation Structure. This structure is known to be quadratically stabilizable and is a rich class, including lowertriangular and upper-triangular structures (which correspond to the so-called backstepping and forwarding in nonlinear control) as special cases. T...

Robust output tracking control for the systems with uncertainties

A new robust tracking control is proposed for the minimum phase dynamical systems with parameter uncertainties and unmatched disturbance, where only the input±output measurement of the system is employed. The system parameters may vary slightly around their corresponding nominal values. The disturbance is assumed to be bounded. However, the upper and lower bounds are unknown. First, the frame o...

Output Feedback Control of Parabolic PDE Systems with Input Constraints

This paper proposes a methodology for output feedback control of parabolic PDE systems with input constraints. Initially, Galerkin’s method is used for the derivation of a finite-dimensional ODE system that captures the dominant dynamics of the PDE system. This ODE system is then used as the basis for the synthesis, via Lyapunov techniques, of stabilizing bounded output feedback control laws th...

Robust Consensus of Linear Multi-Agent Systems under Input Constraints or Uncertainties

This paper proposes a new approach to analyze and synthesize robust consensus control laws for general linear leaderless multiagent systems (MASs) subjected to input constraints or uncertainties. First, the MAS under input constraints or uncertainties is reformulated as a network of Lur’e systems. Next, two scenarios of communication topology are considered, namely undirected and directed cycli...
