Peaking Attenuation in High-Gain Observers Using Adaptive Saturation: Application to a Ball and Wheel System
Despite providing robustness, high-gain observers impose a peaking phenomenon, which may cause instability, on the system states. In this paper, an adaptive saturation is proposed to attenuate the undesirable mentioned phenomenon in high-gain observers. A real-valued and differentiable sigmoid function is considered as the saturating element whose parameters (height and slope) are adaptively tu...
متن کاملEffects of a nonhomogeneous gain saturation law on predicted performance of a high-gain and a low-gain laser systems.
A modified Rigrod theory that uses a nonhomogeneous gain saturation law is used to model outcoupled, total, and intracavity power from a high-gain and a low-gain cw HF chemical laser with good accuracy. The homogeneous gain saturation law is found to have significant limitations when used to model total power data over a wide range of threshold gain values. The use of a nonhomogeneous gain satu...
متن کاملAstigmatically compensated, high gain cooperative upconversion laser
In recent years a variety of schemes have been explored for compact, short-wavelength laser sources in solids. These include wide gap semiconductor diode lasers,* nonlinear generation of optical harmonics by phase matching,2 quasiphase matching,3 and upconversion lasers in bulk media4 and fibers.5 In practical terms, while all these approaches have shown promise, all currently exhibit important...
متن کامل-Gain of Double Integrators With Saturation Nonlinearity
This note uses quadratic surface Lyapunov functions (SuLFs) to efficiently check if a double integrator in feedback with a saturation nonlinearity has L -gain less than > 0. We show that for many such systems, theL -gain is nonconservative in the sense that this is approximately equal to the lower bound obtained by replacing the saturation with a constant gain of 1. These results allow the use ...
متن کاملEffect of Massage on Weight Gain in Premature Infants
Introduction After the introduction of surfactant, the survival rate of preterm neonates has increased significantly. This issue attracted much attention towards this fragile population. Many studies have demonstrated that massage plays a role in the weight gain of preterm infants. This study compares the effect of massage therapy on infants who were massaged by a nurse or their mother with tho...
