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

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.

Stochastic dynamic programming with random disturbances

Discussiones Mathematicae Probability and Statistics, 2023
In stochastic dynamic programming problems, the transition function usually depends on the current state, current action, and random factors, referred in this paper as disturbances. For Markov decision processes, the disturbances form a sequence of independent random values.

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

A stochastic approach to small disturbance stability analysis

IEEE Transactions on Power Systems, 1992
A systematic approach to the construction of stochastic models of electric power systems for small disturbance stability analysis is presented. In this study, the cumulative effects of small-magnitude random fluctuations of electrical loads are considered as sources of eventual loss of stability, and a security measure is derived to determine the small-

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 ...

Adaptive disturbance observer‐based control for stochastic systems with multiple heterogeneous disturbances

International Journal of Robust and Nonlinear Control, 2019
SummaryAntidisturbance control problem is discussed for stochastic systems with multiple heterogeneous disturbances, which include the white noise and the disturbance with unknown frequencies and amplitudes. An adaptive disturbance observer is designed to estimate the disturbance with unknown frequencies and amplitudes, based on which, an adaptive ...

Stochastic disturbance observer-based adaptive anti-disturbance control for non-linear systems with stochastic non-harmonic multiple disturbances

Transactions of the Institute of Measurement and Control, 2017
In this paper, the problem of anti-disturbance control is studied for non-linear systems with stochastic multiple disturbances. The multiple disturbances include two types: one is the stochastic harmonic disturbance and the other non-harmonic noise generated by a linear stochastic exogenous system. An adaptive stochastic disturbance observer (ASDO) is
