This paper presents a vibration control design to the string-tip-mass system by using a non-symmetric peakdetector mechanism. Previously, this peak-detector system was used as an easy algorithm to mitigate vibration on ...

Active, passive and semi-active controls have been extensively considered to improve the protection of structures against earthquakes. In this paper, we present a new nonlinear damper, which is then applied to a three-dimensional ...

This paper suggests a novel nonlinear state-fe edback stabilization control law using linear matrix inequalities for a class oftime-delayed nonlinear dynamic systems with Lipschitz nonlinearity conditions. Based on the ...

The paper presents a control strategy for an automotive electronic throttle, a device used to regulate the power produced by spark-ignition engines. Controlling the electronic throttle body is a difficult task because ...

En aquesta tesi, presentem una solució per a dos problemes rellevants en la teoria de control: el problema del cost quadràtic garantit i el problema del control H∞, per a un cert tipus de sistemes. Considerem els ...

This paper presents a mathematical algorithm and an electronic device to study soil resistivity. The system was based on introducing a time-varying electrical signal into the soil by using two electrodes and then collecting ...

We study a stabilizable mechanical system in the vicinity of an equilibrium position. This position, as a rule, is unstable, and the system is underactuated. It is assumed that faults affect the technical process and its ...

An H∞ output feedback control design is presented for mechanisms with backlash, under the presence of external perturbation. Using the static dead-zone model as a simpler model for backlash, the non-linear problem is cast ...

This paper shows the construction of a low-cost, open-source mechanical ventilator. The motivation for constructing this kind of ventilator comes from the worldwide shortage of mechanical ventilators for treating COVID-19 ...
