Predefined-time control of nonlinear systems
Elsevier
[https://doi.org/10.1016/j.aej.2021.12.030]
This work addresses the predefined-time convergence problem for a class of second order nonlinear systems subjected to matched disturbances. A novel family of sigmoid function based terminal sliding surfaces is proposed for which robust fixed time convergence is guaranteed. The stability properties are established through the Lyapunov framework. In the proposed technique, bound on the settling time is user-defined for arbitrary initial conditions.
Full-state modeling and nonlinear control of balloon supported unmanned aerial vehicle
Emerald
Multi-rotor unmanned aerial vehicles (MUAVs) are equipped with controllers but are constrained by smaller flight endurance and payload carrying capability. On the contrary, lighter than air (LTA) aerial vehicles have longer flight times but have poor control performance for outdoor operations. One of the solutions to achieve better flight endurance and payload carrying capability is to augment the LTA balloon to MUAV.
Robust Decentralized Nonlinear Formation Control of Multiagent Quadrotor
IEEE
In this article the leaderless formation protocol is proposed for a class of square multi-input multi-output nonlinear multiagent systems with an undirected communication graph. The six degree of freedom underactuated nonlinear model of multiagent quadrotor is considered.The sliding mode-based finite-time position, altitude and heading formation is established based on Lyapunov stability theory.

Comprehensive study of skid-steer wheeled mobile robots development and challenges
Emerald
This article provides a comprehensive and unified presentation of recent developments in skid-steer wheeled mobile robots (SSWMR) with regard to its control, guidance and navigation for the researchers who wish to study in this field. Different prospects of SSWMR have been discussed including its design, application, locomotion, control, navigation and guidance.
Robust output feedback control of fixed-wing aircraft
Emerald
Feedback linearization-based state feedback (SFB) controller is considered along with a robust outer loop control which is designed using Lyapunov’s second method. A high-gain observer (HGO) in accordance with the separation principle is used to implement the output feedback (OFB) control scheme. The robustness of the controller and observer is assessed by introducing uncertain aerodynamics coefficients in the dynamic model. The proposed scheme is validated using MATLAB/SIMULINK.

Design and Modeling of Robust Multi Degree of Freedom Micro Gyroscope with Wide Bandwidth
IEEE.
Micro gyroscopes are among the rapidly aggrandizing field of the micro electro mechanical systems (MEMS), which is procured with its extensive range of applications around the globe. This paper depicts an innovated approach of designing and modeling of a novel brawny multi-mass gyroscope to acquire dynamic motion amplification and spacious bandwidth.
Modelling Inspiration and Expiration Mechanism of Lungs using Bond Graph
IEEE.
In proposed work, inspiration and expiration mechanism of lungs has been modelled using Bond Graphs. Lung segments are assigned Hydraulic analogies using cylinders and accumulators. Upper airway from nostrils to trachea is modelled as single cylinder having resistance and associated compliance effect. Trachea to lower lung segment consists of 23 generations of airways.Model is capable of predicting the true PV curves and thus leading to screening of lungs diseases.
Bond Graph Modeling of Lungs
IEEE.
Mathematical model of lungs is used to distinguish the pulmonary diseases. In this work bond graph model of breathing mechanism . Hydraulic analogies are allocated to lungs using cylinders and accumulators. In this study, 2 generations are considered with resistance, compliance and inertial effect. These generations are modeled with cylinders with decreasing sizes. Model can be used for clinical trials with any existing mechanical ventilator.
