... be enhanced. During changes in the rotor spin frequency, fundamental harmonics of the flexible rotor are also excited. Their amplitude is much higher compared to steady-state unbalanced vibrations, which can accelerate the wear and tear of components of EAs. By using feedback controllers, the amplitude...

... by these devices that affect G levels. This work evaluates the effectiveness of two control systems for the case where critical inputs are unmeasured. This work compares and evaluates two predictive feedback control (FBC) algorithms in two unmeasured input studies. In the first study, the process is a dynamic...

...Pipitone Emiliano Fig. 4 Feedback control structure A proportional integral derivative (PID) controller was chosen among the feedback control structures for its simplicity and robustness. In the general structure of a feedback control, as represented in Fig. 4 , the controller...

... systems. Due to design, fabrication, and also runtime uncertainties, feedback control schemes must be incorporated to ensure reliability and accuracy of LOCs for practical use. This paper introduces the basics of the control analysis and design of the DMS, which is a relatively unexplored area in digital...

... variance (MV) related feedback control techniques, employing a NN to predict PPP from various engine signals: air bleed valve (ABV), manifold absolute pressure (MAP), and the ionization current signal. The controller is designed to use integral action for tracking of PPP while reducing the variance...

...Sue Ann Campbell; Stephanie Crawford; Kirsten Morris We consider an experimental system consisting of a pendulum, which is free to rotate 360 deg , attached to a cart. The cart can move in one dimension. We study the effect of friction on the design and performance of a feedback controller...

... are proposed to realize stable inner-loop dynamics, a linear state feedback control scheme and a switching control scheme. Through numerical simulations and estimation of the region of attraction, it is shown that effective feedback schemes can be constructed. In comparison to existing control schemes...
