New Synthesis of Linear Decoupled Control Systems

A New Non-linear Control of the Four-Leg Inverter with Decoupled Model and Fast Dynamic Response for PV Generation Systems

Distributed generation (DG) will play an important role in future power generation systems, especially in stand-alone applications. Three phase four-leg inverter is a well-known topology which can be used as an interface power converter for DGs. Thanks to the fourth leg to provide the neutral path, the four-leg inverter is able to supply balanced loads as well as unbalanced loads. In this paper...

A new Approach to the Multi-Objective Control of Linear Singular Perturbation Systems

Control-Law Synthesis for Linear Hybrid Systems

The behavior of hybrid systems is described by means of continuous and discrete variables. A number of di erent philosophies have been pursued in order to establish a mathematical framework that is able to handle both, continuous and discrete processes. These range from the construction of hybrid automata [1] and structures [2] over the de nition of interfaces between the continuous and the dis...

Universal Control of Decoupled Quantum Systems

We show that if one can perform a restricted set of fast manipulations on a quantum system, one can implement a large class of dynamical evolutions by effectively removing or introducing selected Hamiltonians. The procedure can be used to achieve universal noise-tolerant control based on purely unitary open-loop transformations of the dynamics. As a result, it is in principle possible to perfor...

Optimal Finite-time Control of Positive Linear Discrete-time Systems

This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...
