... controllers was compared based on the stability parameters to validate the proposed actuation system. Finally, simulation results suggest that the LQR approach can be used to synthesize a suitable and simple controller for this application. Contributed by the Dynamic Systems Division of ASME...

... Through the simulation and analysis, the error for the sine response with β =  0.1 β nom is shown in Fig. 25 that represents very good stability behavior. Then, to show the limiting value for satisfying the stability condition, the maximum error is illustrated in Fig. 26 as function of the bulk...

... for the detection and characterization of surface and subsurface cracks. In this paper, heating behaviors of edge cracks, excited by pulsed eddy currents, are examined using numerical simulations. The simulations are performed using COMSOL multiphysics finite element method simulation software using the AC/DC...

... and Garg). This model is developed using the analysis of intravital video microscopy. The first two papers under Model Validation and Estimation introduce new metrics for the comparison of time histories that result from the simulation of dynamic systems (Sarin et al.; McCusker et al.). The next paper...

...Laura Celentano; Raffaele Iervolino In this paper the possibility of simulating the robot forward dynamics by making use of the inertia matrix and of the kinetic energy gradient only is demonstrated. Such method is shown to be simpler and numerically more efficient than the classical approaches...

...Youping Mei, Graduate Student; Kim A. Stelson, Professor Bar lapping is a key process in fabricating computer hard disk drive heads. The purpose is to remove a small amount of material so that the transducer stripe height variation across the bar is minimized. In this article a method of simulating...

... The dynamic response of the DLPR is simulated by solving the model equations, for a given set of initial conditions and a forcing function (the command pressure at the dome as function of time). The numerical integration was carried out by a fourth-order Runge–Kutta algorithm 9 . The physical...
