Robust mixed order backstepping control of non-linear systems
(Institution of Engineering and Technology, 2018-06-12)
Robust backstepping control of non-linear systems with derivation orders (commensurate or non-commensurate) lying at interval (0, 2) is proposed in this study. The stability and robustness properties are proved using a ...
Robust adaptive passivity-based (PID)-D-lambda control
(Wiley, 2020)
In this article, we develop proportional, fractional-integral, and derivative (PI lambda D) controllers for the regulation and tracking problems of nonlinear systems. The analytic results are obtained by extending the ...
Adaptive synchronization of Lorenz systems using a reduced number of control signals and parameters without knowing bounds on system parameters and trajectories
(Oxford University Press, 2018-03)
This article analyzes the synchronization of two Lorenz systems with unknown but matched parameters. The proposed control strategies use a reduced number of control signals and adjustable parameters, without any assumption ...
Adaptive synchronization of fractional Lorenz systems using a reduced number of control signals and parameters
(Elsevier, 2016)
This paper analyzes the synchronization of two fractional Lorenz systems in two cases: the first one considering fractional Lorenz systems with unknown parameters, and the second one considering known upper bounds on some ...
Convergence of fractional adaptive systems using gradient approach
(Elsevier, 2017)
Conditions for boundedness and convergence of the output error and the parameter error for various Caputo's fractional order adaptive schemes based on the steepest descent method are derived in this paper. To this aim, the ...
Taylor polynomial approximation and adaptive passivity-based control applied to the level regulation of a conical tank
(Wiley, 2017)
The techniques of Taylor polynomial approximation (TPA) and adaptive passivity-based controller (APBC) are combined in this study and applied to the level regulation of a conical tank. The design and comparative experimental ...
Fractional adaptive systems in the presence of bounded disturbances and parameter variations
(Wiley, 2017)
This paper presents the analysis of fractional adaptive systems in the presence of bounded disturbances and parameter variations. Fractional adaptive systems are analyzed using the error model approach, to give generality ...
Normalized model reference adaptive control applied to high starting torque scalar control scheme for induction motors
(MDPI, 2022)
Recently, a novel high-starting torque scalar control scheme (HST-SCS) for induction motor(s) (IM) emerged. It expands the scalar control application field beyond centrifugal pumps, blowers, and fans, moving, for instance, ...
Control basado en pasividad para una clase de sistemas no lineales y su aplicación a la regulación de nivel de un estanque cónico
(Comité Español de Automática, 2018)
En este artículo científico se proponen dos estrategias de control basado en pasividad, una adaptable y la otra no adaptable para cierta clase de sistemas no lineales. A diferencia de la estrategia de control no adaptable, ...
Robustness and convergence of fractional systems and their applications to adaptive schemes
(De Gruyter, 2017)
Our general aim is to give sufficient conditions for robustness behavior and convergence to the equilibrium point of linear time-varying fractional system's solutions. We approach this problem using as a framework a series ...
