Convergence of Consensus Models With Stochastic Disturbances

IEEE Transactions on Information Theory, 2010
We consider consensus algorithms in their most general setting and provide conditions under which such algorithms are guaranteed to converge, almost surely, to a consensus. Let {A(t), B(t)} ∈ RN×N be (possibly) stochastic, nonstationary matrices and {x(t), m(t)} 6 RN×1 be state and perturbation vectors, respectively.

Optimal Rejection of Stochastic and Deterministic Disturbances

Journal of Dynamic Systems, Measurement, and Control, 1997
The problem of optimal H2 rejection of noisy disturbances while asymptotically rejecting constant or sinusoidal disturbances is considered. The internal model principle is used to ensure that the expected value of the output approaches zero asymptotically in the presence of persistent deterministic disturbances.

Adaptive stochastic disturbance accommodating control

International Journal of Control, 2011
This article presents a Kalman filter based adaptive disturbance accommodating stochastic control scheme for linear uncertain systems to minimise the adverse effects of both model uncertainties and external disturbances. Instead of dealing with system uncertainties and external disturbances separately, the disturbance accommodating control scheme lumps

Amorphous computing in the presence of stochastic disturbances

Biosystems, 2014
Amorphous computing is a non-standard computing paradigm that relies on massively parallel execution of computer code by a large number of small, spatially distributed, weakly interacting processing units. Over the last decade or so, amorphous computing has attracted a great deal of interest both as an alternative model of computing and as an ...

SELF-TUNING CONTROLLER FOR PLANTS DISTURBED BY NONSTATIONARY STOCHASTIC DISTURBANCE

IFAC Proceedings Volumes, 1982
The paper expands some previous work on the design of self-tuning controllers (STC) for the case where the plant may be disturbed by nonstationary stochastic disturbances. The considered stochastic disturbances are modelled by passing a white noise process through autoregresive integrated moving average (ARIMA) filters.

Stochastic Disturbance Decoupling

1990
For a linear control system having white Gaussian processes as its system and measurement disturbances, we first formulate a stochastic version of the usual disturbance decoupling problem. More precisely, contructing a Kalman-Bucy filter to generate the best estimate of the state, we consider the problem of finding a feedback of the state estimate so ...

Stabilization of stochastic nonholonomic systems with unknown stochastic disturbances

2008 27th Chinese Control Conference, 2008
This paper deals with the output feedback stabilization problem for the stochastic nonholonomic systems with unknown stochastic disturbances. The objective is to design the almost global asymptotical output feedback controllers in probability for the systems by output feedback. The switching control strategy based on the output measurement of the first

$H_\infty$ Control for Stochastic Systems with Disturbance Preview

SIAM Journal on Control and Optimization, 2020
The declared purpose of this paper is to generalize to a stochastic setting the work of \textit{G. Tadmor} and \textit{L. Mirkin} [IEEE Trans. Autom. Control 50, No. 1, 19--28 (2005; Zbl 1365.93149); 29--40 (2005; Zbl 1365.93150)] who gave a solvability condition for the deterministic case along with an analytic solution, using two Riccati equations ...

Disturbance Observer‐Based Elegant Anti‐Disturbance Control for Stochastic Systems with Multiple Disturbances

Asian Journal of Control, 2017
AbstractDisturbance observer‐based elegant anti‐disturbance control (DOBEADC) scheme is proposed for a class of stochastic systems with nonlinear dynamics and multiple disturbances. The stochastic disturbance observer based on pole placement is constructed to estimate disturbance which is generated by an exogenous system.

Composite hierarchical anti-disturbance control for stochastic systems with multiple disturbances

Transactions of the Institute of Measurement and Control, 2017
A class of stochastic systems with multiple disturbances, which includes white noises and disturbances whose time derivative is bounded, is considered in this paper. To estimate the unknown bounded disturbance, a stochastic disturbance observer is proposed.
