چکیده

This paper studies the notion of central Pa controllers in the chain-scattering framework. Since in the chain-scattering framework the :&a control problem is equivalent to a factorisation problenl that yields non-unique factors, it is important to somehow pin down these factors so that the resulting central controller is uniquely defined and corresponds to the central and minimum-entropy coiltroller frequently discussed in the literature. In so doing, we devise a procedure for the selection of a single uniquely specifiable ,Fm coiltroller in the chain-scattering framework. The chain-scattering frainework is important because it has a distinct advantage over state-space based methods for some applications in that it poses and solves the .;4", coiltrol problem entirely in an operator-theoretic setting, thereby allowing LIS to conte~nplate direct changes of the frequency domain syinbols rather than changes in the corresponding state-space matrices.

Optimization of the Lyapunov Based Nonlinear Controller Parameters in a Single-Phase Grid-Connected Inverter

In this paper, optimization of the backstepping controller parameters in a grid-connected single-phase inverter is studied using Imperialist competitive algorithm (ICA), Genetic Algorithm (GA) and Particle swarm optimization (PSO) algorithm. The controller is developed for the system based on state-space averaged model. By selection of a suitable Lyapunov function, stability of the proposed con...
