Observer-Based Adaptive Control of Uncertain Nonlinear Systems Via Neural Networks

IEEE Access, 2018
In this paper, a novel observer-based control strategy is proposed for a class of uncertain continuous-time nonlinear systems based on the Hamilton-Jacobi-Bellman (HJB) equation.

An Uncertain Data Integration System [PDF]

, 2012
Data integration systems offer uniform access to a set of autonomous and heterogeneous data sources. An important task in setting up a data integration system is to match the attributes of the source schemas. In this paper, we propose a data integration system which uses the knowledge implied within functional dependencies for matching the source ...

Probabilistic Control for Uncertain Systems [PDF]

Journal of Dynamic Systems, Measurement, and Control, 2012
In this paper a new framework has been applied to the design of controllers which encompasses nonlinearity, hysteresis and arbitrary density functions of forward models and inverse controllers. Using mixture density networks, the probabilistic models of both the forward and inverse dynamics are estimated such that they are dependent on the state and ...
