En este trabajo se muestra la aplicación de una técnica para la regulación de frecuencia en controladores desli- zantes en un convertidor elevador. Dicha estrategia, la cua l había sido propuesta teóricamente para sistemas ...

This report considers the analytical approximation of unstable limit cycles that may appear in Abel equations written in the normal form. The procedure uses an iterative approach that takes advantage of the contraction ...

The rejection of the undesirable effects of sudden load changes undergone by power inverters requires control techniques able to recover regular operation with a low transient error, in a short number of periods and ...

The extension and size of the power grid is expected to increase in the near future. Managing such a system presents challenging control problems that, so far, have been approached with classical control techniques. However, ...

We describe a multicellular approach to control a target cell population endowed with a bistable toggle-switch. The idea is to engineer a synthetic microbial consortium consisting of three different cell populations. In ...

When an oscillator switches abruptly between different frequencies, there is some ambiguity in deciding how the system should be modelled at the switch. Here we describe two seemingly natural models of a switch in a simple ...

This work deals with the design and analysis of a controller for a shunt active power filter. The design is based on combined feedforward and feedback actions, the last using repetitive control, and aims at the obtention ...

It is well known that in implementations of sliding mode controllers using hysteresis comparators, when the hysteresis band amplitude tends to zero the real dynamics tends to the ideal sliding dynamics. However, in real ...

This paper proposes a decentralized, passivity-based cont rol design for power stations in a multi-terminal High Voltage Direct Current transmissi on system. The control algorithm is shown to asymptotically stabilize the ...

The study of periodic solutions with constant sign in the Abel equation of the second kind can be made through the equation of the first kind. This is because the situation is equivalent under the transformation x 7¡æ ...
