Improved gradient descent algorithms for time-delay rational state-space systems: Intelligent search method and momentum method (2020)
Journal Article
Chen, J., Zhu, Q., Hu, M., Guo, L., & Narayan, P. (2020). Improved gradient descent algorithms for time-delay rational state-space systems: Intelligent search method and momentum method. Nonlinear Dynamics, 101, 361-373. https://doi.org/10.1007/s11071-020-05755-8

This study proposes two improved gradient descent parameter estimation algorithms for rational state-space models with time-delay. These two algorithms, based on intelligent search method and momentum method, can simultaneously estimate the time-dela...

Dynamic mesh framework for morphing wings CFD - User defined function (2020)
Digital Artefact
Abdessemed, C., Yao, Y., Bouferouk, A., & Naryan, P. (2020). Dynamic mesh framework for morphing wings CFD - User defined function

This project contains the user-defined functions (UDF) necessary to perform unsteady computational fluid dynamics (CFD) analysis of dynamically morphing wings equipped with morphing flaps. There are three UDFs for each of the following application... Read More about Dynamic mesh framework for morphing wings CFD - User defined function.

An Investigation of a Morphing Flapped Wing (2020)
Presentation / Conference
Madi, F., Kanaa, Z., Narayan, P., & Yao, Y. (2020, February). An Investigation of a Morphing Flapped Wing. Paper presented at Aerospace Europe Conference (AEC2020), Bordeaux, France

This study investigated the design, development, and validation of an alternative method to achieve morphing in wings through the implementation of a sliding mechanism concept. Performance was tested at a specific Reynolds number (Re = 0.62 × 106). M... Read More about An Investigation of a Morphing Flapped Wing.

A composite feedback approach to stabilize nonholonomic systems with time varying time delays and nonlinear disturbances (2020)
Journal Article
Rasoolinasab, S., Mobayen, S., Fekih, A., Narayan, P., & Yao, Y. (2020). A composite feedback approach to stabilize nonholonomic systems with time varying time delays and nonlinear disturbances. ISA Transactions, 101, 177-188. https://doi.org/10.1016/j.isatra.2020.02.009

In this work, we propose a robust stabilizer for nonholonomic systems with time varying time delays and nonlinear disturbances. The proposed approach implements a composite nonlinear feedback structure in which a linear controller is designed to yiel...
