AbstractNumerous techniques have been proposed in the literature to improve the performance of high‐gain observers with noisy measurements. One such technique is the linear extended state observer, which is used to estimate the system's states and to account for the impact of internal uncertainties, undesirable nonlinearities, and external disturbances. This observer's primary purpose is to eliminate these disturbances from the input channel in real‐time. This enables the observer to precisely track the system states while compensating for the various sources of uncertainty that can influence the system's behaviour. So, in this paper, a novel nonlinear higher‐order extended state observer (NHOESO) is introduced to enhance the performance of high‐gain observers under noisy measurement conditions. The NHOESO is designed to observe the system states and total disturbance while eliminating the latter in real time from the input channel. It is capable of handling disturbances of higher‐order derivatives, including internal uncertainties, undesirable nonlinearities, and external disturbances. The paper also presents two innovative schemes for parametrizing the NHOESO parameters in the presence of measurement noise. These schemes are named time‐varying bandwidth NHOESO (TVB‐NHOESO) and online adaptive rule update NHOESO (OARU‐NHOESO). Numerical simulations are conducted to validate the effectiveness of the proposed schemes, using a nonlinear uncertain system as a test case. The results demonstrate that the OARU technique outperforms the TVB technique in terms of its ability to sense the presence of noise components in the output and respond accordingly. However, it is noted that the OARU technique is slower than the TVB technique and requires more complex parameter tuning to adaptively account for the measurement noise.

AbstractRevisiting the study of quiescent optical solitons with quintuple-power-law self-phase modulation and nonlinear chromatic dispersion is the focus of the current paper. The soliton solutions to the model are revealed through the intermediary Jacobi’s elliptic functions using the enhanced direct algebraic method. The intermediary Weierstrass’ elliptic functions are used by the sub-ODE approach to reveal such quiescent soliton solutions.

AbstractThe focus of the current paper is on the retrieval of quiescent optical solitons from Fokas–Lenells equation with nonlinear chromatic dispersion and having quadratic–cubic as well as quadratic–cubic–quartic forms of self-phase modulation structures. Two integration algorithms are implemented to carry out to seek such soliton solutions. They are the enhanced Kudryashov’s approach and the projective Riccati equation approach. In this context, both linear temporal evolution and generalized temporal evolution effects are addressed. A full spectrum of quiescent optical solitons is thus recovered.

AbstractThis paper recovers the gap solitons in fiber Bragg gratings for the concatenation model that comes with Kerr-law of self-phase modulation by the usage of enhanced direct algebraic approach. A full spectrum of optical solitons are thus recovered. The existence criteria of such solitons, in the form of parameters constraints, that naturally emerged during the course of derivation, are presented. A few numerical simulations supplement the mathematical analysis.

AbstractThe current paper recovers a variety of highly dispersive optical solitons with non–local form of self–phase modulation structure and having polarization–mode dispersion. Two integration approaches have made this retrieval successful. The soliton solutions are enlisted and presented with the parameter constraints that ensures their existence. A shortcoming of these approaches is that neither one revealed dark soliton solution to the model. This limitation suggests the need to explore additional approaches to obtain dark soliton solutions. This is one of several future avenues of research for the model in this work.

AbstractThis paper recovers optical soliton solutions in magneto-optic waveguides that maintain the generalized version of anti-cubic form of nonlinear self-phase modulation structure. The csch method as well as the tanh–coth approach recovers the singular and dark-singular straddled optical solitons in such forms of magneto-optic waveguide. The existence criteria of such solitons are also presented.

A quadruple tank system using a new anti-disturbance technique called Modified Active Disturbance Rejection Control (MADRC) is introduced in this paper, along with a detailed examination of its design and hardware (H/W) implementation. To maintain the water levels in the quadruple system at predefined targets while minimizing the impact of external disturbances, the proposed scheme employs two advanced nonlinear controllers, enhanced tracking differentiator schemes, and newly developed nonlinear extended state observers (NNLESO). The proposed modified ADRC method outperforms the alternatives, according to the experimental data. With an improved ability to reject disturbances, the STC-ADRC approach reduced the output response oscillation to 3.33% of the equilibrium value. The NLPD-ADRC method, on the other hand, effectively managed system dynamics under disturbance conditions, as evidenced by a 4.666% oscillation. Additionally, disturbances had a significant impact on the S-fal-ADRC scheme, highlighting how distinct the proposed control mechanisms were in terms of performance. This work represents a significant advancement in the control of interconnected non-linear quadruple tank systems and proves that the MADRC method is effective in enhancing system stability and disturbance attenuation.

AbstractThis paper recovers highly dispersive 1-soliton solutions with differential group delay and having polynomial law of self-phase modulation structure. Two integration approaches have made this retrieval possible. They are the extended auxiliary equation method and Kudryashov’s algorithm. Together, these yielded a full spectrum of 1-soliton solutions along with their respective parameter constraints that are also presented.

AbstractThe paper obtains highly dispersive optical solitons with nonlocal law of self—phase modulation with differential group delay. The Sardar sub equation approach is the integration algorithm that makes this retrieval possible. The parameter constraints that naturally emerge from the scheme are also enlisted. The current work is thus a sequel to the previous paper that is with Kerr law of self—phase modulation structure.

AbstractThe current paper recovers soliton solutions in magneto-optic waveguides having generalized form of Kudryashov’s self-phase modulation structure. The retrieval of soliton solutions is achieved by the well-known and primitive $$G^{\\prime }/G$$ G ′ / G -expansion scheme. The intermediary functions that made this retrieval possible are Jacobi’s elliptic functions and Weierstrass’ elliptic functions. The parameter constraints for the solitons to exist are also presented.

AbstractThe paper addressed the long-lost model that recovers optical dromions, namely the Radha–Lakshmanan equation. The fractional temporal evolution gave way to the slow evolution of such dromions. The simplest equation algorithm yielded such solutions that are enlisted and supported with numerical simulations.

This paper recovers dark-singular straddled optical solitons for the dispersive concatenation model with power-law of self-phase modulation using the tanh-coth approach. The individual dark or singular solitons are not supported by the model for power-law unless this law collapses to Kerr law as proven with the usage of undetermined coefficients, earlier.
