Analysis and Control of Linear Time Periodic System using Normal FormsInternational Journal of Dynamics and Control - Tập 10 - Trang 1626-1636 - 2022
Susheelkumar Cherangara Subramanian, Sangram Redkar
Multiple techniques have been developed in the past towards stability and control of linear time periodic systems. Though the method of normal forms was predominantly applied to nonlinear equations, in this work, it is utilized to transform a linear time varying system with periodic coefficients to a time-invariant system (similar to a Lyapunov-Floquet transformation). The direct application of ti...... hiện toàn bộ
A novel hybrid learning based Ada Boost (HLBAB) classifier for channel state estimation in cognitive networksInternational Journal of Dynamics and Control - Tập 9 - Trang 299-307 - 2020
S. Vadivukkarasi, S. Santhi
Spectrum sensing, through efficient channel estimation methods utilizing cognitive radio networks, has become an increasingly researched area in recent times. This has become more pronounced in recent times, especially with increasing scarcity in availability of radio frequency spectrum. Wireless state of the art communication standards demand high bandwidth to provide seamless connectivity and hi...... hiện toàn bộ
A new fuzzy control system based on the adaptive immersion and invariance control for brushless DC motorsInternational Journal of Dynamics and Control - Tập 9 - Trang 807-817 - 2020
Akram Sedaghati, Naser Pariz, Mehdi Siahi, Roohollah Barzamini
In this study a novel type-2 fuzzy control approach on basis of the adaptive immersion and invariance (I&I) control method is proposed to control of brushless DC motors (BLDCMs). The parameters of the mathematical model of the BLDCM are considered to be unknown and furthermore the dynamics of BLDCM are disturbed by changes of some variables such load torque and phases resistance. The stability is ...... hiện toàn bộ
Combination therapy of pegylated interferon and lamivudine and optimal controls for chronic hepatitis B infectionInternational Journal of Dynamics and Control - Tập 6 - Trang 354-368 - 2017
Kalyan Manna, Siddhartha P. Chakrabarty
A model for combination therapy of pegylated interferon and lamivudine is presented in this paper. A critical drug efficacy in terms of the parameters of the model comprising of coupled ordinary differential equations is obtained. The dynamics of viral load is greatly impacted by the relation of the efficacies of the individual drugs vis-a-vis the critical efficacy. A control problem is formulated...... hiện toàn bộ
Bifurcation surfaces and multi-stability analysis of state feedback control of PMSMInternational Journal of Dynamics and Control - Tập 7 - Trang 276-294 - 2018
Wahid Souhail, Hedi Khammari, Mohamed Faouzi Mimouni
The paper presents a thorough bifurcation analysis of detailed permanent magnet machine with feedback drive, showing the effect of different control and system parameters on the bifurcation and the associated system stability. This study addresses the nonlinear behavior of the PMSM under parametric variation. The analysis of the phase space and parametric singularities are developed in order to id...... hiện toàn bộ
Qualitative analysis of a fractional-order two-strain epidemic model with vaccination and general non-monotonic incidence rateInternational Journal of Dynamics and Control - Tập 11 Số 4 - Trang 1532-1543 - 2023
Sahnoune, Mohamed Yasser, Ez-zetouni, Adil, Akdim, Khadija, Zahid, Mehdi
In this paper, a fractional-order two-strain epidemic model with vaccination and general non-monotonic incidence rate is analyzed. The studied problem is formulated using susceptible, infectious and recovered compartmental model. A Caputo fractional operator is incorporated in each compartment to describe the memory effect related to an epidemic evolution. First, the global existence, positivity a...... hiện toàn bộ
