Reconfigurable multivibrator element based on chaos control; Elemento multivibrador reconfigurable basado en control de caos Campos Cantón, Eric; Campos Cantón, Isaac; Barajas Ramírez, Juan Gonzalo; Femat Flores, Alejandro Ricardo "A reconfigurable element based on nonlinear (chaotic) dynamics is adapted to implement the three different multivibrator configurations. A nonlinear dynamical system, under parameter modulating control, operates as a tunable oscillator with different dynamical regimes which in turn provide the different multivibrator configurations (monostable, astable, and bistable). The reconfigurable multivibrator is realized as a tunable circuit which includes an input stage for receiving at least one input voltage signal and an output stage that produces a digital two-level electric output signal. The all-in-one reconfigurable multivibrator device consisting of a nonlinear oscillator circuit electrically coupled to the input/output circuitry is used in at least, but not limited to three basic applications, namely, an irregular width pulse generator, a rising flank trigger and a full RS flip-flop device."; "Un elemento reconfigurable basado en dinámica nolineal (caótico) es adaptado para implementar los tres diferentes configuraciones de multivibrador. Un sistema dinámico nolineal, bajo un control por modulación paramétrica, opera como un oscilador ajsutable con diferentes regímenes dinámicos, los cuales a su vez producen las diferentes configuraciones de multivibrador (monoestable, aestable, y biestable). El multivibrador reconfigurable se realiza como un circuito ajustable el cual incluye una etapa de entrada para recibir al menos una señal de voltaje de entrada, y una etapa de salida, la cual produce una señal de salida digital electrónica de dos niveles. El dispositivo multivibrador reconfigurable todo-en-uno que consiste de un circuito oscilador nolineal eléctricamente acoplado a una circuitería de entrada/salida es utilizado en al menos, pero no limitado a, tres aplicaciones básicas, estas son, un generador de pulsos con ancho irregular, un disparador de flanco de subida, y un dispositivo lógico RS completo biestable (flip-flop)."

Reconfigurable dynamical logic gate with linear core Campos Cantón, Eric; Campos Cantón, Isaac; Rosu Barbus, Haret-Codratian "A dynamically reconfigurable linear core logic gate is a device that allows logical outputs dependent upon configurable parameters set within device. The device is comprised of three blocks: The first block receives at least one input signal and determines whether the signal o signals are low or high in comparison with a threshold reference signal. The second block sums the logic signals of the first block with an offset signal. The third block determines if the sum realized in the second block is a low or high by checking whether the sum falls within a predetermined interval."

Repetitive controller to compensate for odd harmonics Leyva Ramos, Jesús; Escobar Valderrama, Gerardo "A repetitive controller scheme with negative feedback and feedforward introduces infinitely many poles on the imaginary axis located at the resonant peaks. The feedforward introduces zeros, which produce notches located in between two consecutive resonant peaks. The latter has the advantage of making the controllers more selective, in the sense that the original overlapping (appearing at the valleys) or interaction between consecutive resonant peaks is removed by the notches. This would allow, in principle, peaks of higher gains and slightly wider bandwidth, avoiding, at the same time, the excitation of harmonics located in between two consecutive peaks. A negative feedback compensator with feedforward is especially useful when only the compensation of odd harmonics is required, but not the even harmonics, like in many power electronic systems.; In contrast, the positive feedback controller would try to reinject, and indeed amplify, any small noise, which has components on the even frequencies. The negative feedback repetitive controller includes a simple Low Pass Filter (LPF). This modification restricts the bandwidth of the controller, and at the same time reinforces the stability when the controller is inserted in a closed-loop system."
