Online identification and nonlinear control of the electrically stimulated quadriceps muscle [PDF]
, 2005 A new approach for estimating nonlinear models of the electrically stimulated quadriceps muscle group under nonisometric conditions is investigated. The model can be used for designing controlled neuro-prostheses. In order to identify the muscle dynamics

Passivity Analysis of Nonlinear Euler-Bernoulli Beams [PDF]
Modeling, Identification and Control, 2002 The Lagrangian equations for distributed-parameter systems based on Hamilton's principle are developed. These equations are subsequently used to derive nonlinear models for beams. The passivity properties of the flexible mechanical systems based on their

Amplitude stabilization of micromechanical oscillators using engineered nonlinearity
Physical Review Research, 2021 Micromechanical oscillators provide periodic output signals for clocks and sensors by vibrating in a single mechanical mode. The mode is conventionally excited into self-sustained oscillations and stabilized with an external electronic feedback loop.

Dissipative solitons in pattern-forming nonlinear optical systems : cavity solitons and feedback solitons [PDF]
, 2005 Many dissipative optical systems support patterns. Dissipative solitons are generally found where a pattern coexists with a stable unpatterned state. We consider such phenomena in driven optical cavities containing a nonlinear medium (cavity solitons ...

AIP Advances, 2020 The nonlinear resonance response of electromechanical structures, such as Duffing resonators, can discern both geometrical and internal anomalies, such as the “softening” response attributed to deviations from an ideal parallel plane for the former and ...
