Research ArticleOpen accessIn the keywordsSemi Active Tuned Mass Dampers of Buildings: A Simple Control OptionDemetris Demetriou, Nikolaos Nikitas, Konstantinos Daniel TsavdaridisThe present study investigates the effectiveness of a Proportional-Integral-Derivative (PID) controlled Variable Damping Semi-Active Tuned Mass Damper (VD-STMD) on reducing the vibration response of an earthquake excited multi-storey structure. The effectiveness of the controlled system is evaluated by comparing the structure’s overall dynamic behavior against that of an equivalent similar structure equipped with a conventional optimally designed passive Tuned Mass … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 30 Oct 2015 · 9,652 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,981 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamics of Mechanisms with Cams Illustrated in the Classical DistributionRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,491 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSTATCOM Stabilizer based on Fuzzy Logic Control for Damping Power OscillationPrechanon KumkratugProblem statement: In power systems, there exists a continuous challenge to improve dynamic performance of power system. Approach: Static Synchronous Compensator (STATCOM) is a power electronic based device that has the capability of controlling the power flow through a line. This study applies the Static Synchronous Compensator (STATCOM) to control the power flow during dynamic period. To verify the effect … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 8 Sep 2011 · 7,440 accessesView PDF Cite
