... 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. 2 Indicator evaluation error due to pressure referencing error (2500 rpm, 3 bar BMEP, λ  = 1) Once their optimal values were determined, the indicators were implemented as process variables on a feedback control system, which was realized [ 29 ] by the use...

... 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...

... to cover all possible operating points. Previous engine control research, for example, Refs. 1 2 3 , demonstrated that the use of in-cylinder pressure as a feedback control variable removes the requirement for this laborious task. Further advantages of the use of such feedback include automatic...

...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...

... circuit models proposed by Brayton 23 , or the lossless propagation models discussed by Halanay and Raˇsvan 24 ). When the time needed to transmit information used for feedback control, time delay also arises. This is the case in, for example, master-slave teleoperation of robot, see Anderson...
