Multirate adaptive inferential estimation - Control Theory and Applications [see also IEE Proceedings-Control Theory and Applications], IEE Pr

چکیده
An adaptive inferential algorithm is developed for estimation and control of multirate systems. The output y is measured J times slower than the secondary process output v and the input U, but an output estimate ye is produced at each sampling interval of v and U. Compared with previous work on multirate inferential systems, the proposed algorithm has a more formal theoretical basis. For example, the output y is related to the secondary output U not only through external stochastic disturbances but also through the internal system structure. Convergence properties are formally proven for the case of zero external stochastic disturbances, and a simplified algorithm is proposed for practical applications. Simulated results illustrate the convergence properties of the algorithm and the improvement obtained in simple feedback control systems.

Hybrid adaptive control for tracking of rigid-link flexible-joint robots - Control Theory and Applications [see also IEE Proceedings-Control Theory and Applications], IEE Pr
A hybrid adaptive tracking controller for rigid-link flexible-joint (RLFJ) robot manipulators is designed. The controller is hybrid in the sense that an adaptive indirect controller is used to compensate for parametric uncertainties in the rigid-link equation whereas an adaptive robust controller corrects for the dynamics (i.e. mechanical flexibilities) and parametric uncertainty associated wit...
متن کاملRecursive approach to optimal control problem of multiarea electric energy system - Control Theory and Applications [see also IEE Proceedings-Control Theory and Applications], IEE Pr
A recursive fixed-point-type method is presented to find the optimal control of a statevariable model of the megawatt-frequency control problem of multiarea electric energy systems. The results give the numerical decomposition so that only low-order systems are involved in algebraic computations. This approach is conceptually simple and produces considerable savings of computation.

The aim of the paper is to explore the relationship between the continuous-time Riccati equation and the corresponding discrete-time equation with fast sampling. The interconnection is established by formulating the discrete case using delta operators. The application of these results to the Kalman filtering problem highlights the importance of analogue prefiltering in the sampling process. A s...
متن کاملDecoupling of descriptor systems - Control Theory and Applications [see also IEE Proceedings-Control Theory and Applications], IEE Pr
Using the descriptor standard form, the decoupling problem of the descriptor system by state feedback is studied. The descriptor system is first transformed in controller form and the necessary and sufficient conditions for the descriptor system to be integrator decoupled are obtained. Then, these conditions are shown to be necessary and sufficient for the closed-loop system poles to be assigne...

Multilayered neural networks are used to construct nonlinear learning control systems for a class of unknown nonlinear systems in a canonical form. An adaptive output tracking architecture is proposed using the outputs of the two three-layered neutral networks which are trained to approximate the unknown nonlinear plant to any desired degree of accuracy by using the modified back-propagation te...
