...-to-state stability. Lookup tables, which are widely used to represent the complex nonlinear characteristics of engine systems, appear in their original form in the designed reduced-order observer, and the torsional stiffness of the drive axle shaft is considered in the model-based design procedure...

...A. K. Samantaray; S. S. Dasgupta; R. Bhattacharyya The rotating internal damping or nonconservative circulatory force in a rotor shaft system causes instability beyond a certain threshold rotor spinning speed. However, if the source loading of the drive is considered, then the rotor spin...

... the MHAVC feedforward suppresses steady-state vibration. It is found that there is a range of P and D feedback gains that ensures both MHAVC convergence and closed-loop stability robustness with respect to shaft internal damping induced whirl and misalignment effects. Finally, it is analytically...

... algorithms were based on the assumption of rigidity in the flywheel’s bearings and the satellite structure. This paper provides simulation results and theory, which eliminates this assumption utilizing control algorithms for active vibration control (AVC), flywheel shaft levitation, and integrated power...

...Noah D. Manring; Viral S. Mehta; Frank J. Raab; Kevin J. Graf The objective of this study is to identify the best indexed position of two rotating groups within a tandem axial-piston pump for attenuating the torque ripple amplitude that is exerted on the shaft. By attenuating the torque ripple...
