In this paper, the authors review recent advances in the use of passivity indices in Cyber-physical systems and how they are used in the resilient design of compositional Cvber-phvical systems.Abstract:
Analysis and resilient design of Cyber-physical Systems have greatly benefited from energy based concepts of passivity and dissipativity. Recently, there has been much research devoted to the use of passivity indices in different components of Cyber-physical systems. Passivity indices are measures of passivity, indicating how passive a system is or how far is it from being passive and generalize passivity based methods to systems that might not be passive. In this paper, we will review recent advances in the use of passivity indices in Cyber-physical systems. We will overview how the indices have been defined and applied to different components of Cyber-physical systems and how they are used in the resilient design of compositional Cvber-phvsical systems.read more

Passivity-based Voltage Controller for Tidal Energy Conversion System with Permanent Magnet Synchronous Generator
TL;DR: In this paper, a passivity-based voltage controller (PBVC) was applied to the machine-side to ensure asymptotic convergence to the MPPT, and a proportional integral derivative (PID) was added to design a desired torque dynamic in order to guarantee a fast convergence and stability of the closed loop system, which allowed to the PMSG to operate at an optimal speed.

A Data-driven Adaptive Controller Reconfiguration for Fault Mitigation: A Passivity Approach
Hasan Zakeri,Panos J. Antsaklis +1 more
TL;DR: The proposed algorithm detects changes in the input-output behavior of the system, whether due to faults or malicious attacks and then reacts by reconfiguring the existing controller by relying only on the system's input and output data.

Fuzzy Supervisory Passivity-Based High Order-Sliding Mode Control Approach for Tidal Turbine-Based Permanent Magnet Synchronous Generator Conversion System
Youcef Belkhier,Abdelyazid Achour,Rabindra Nath Shaw,Nasim Ullah,Md. Shahariar Chowdhury,Kuaanan Techato +5 more
TL;DR: A novel optimal fuzzy supervisor passivity-based high order sliding-mode controller to address problems faced by conventional techniques such as PI controls in the machine side, which treats the mechanical characteristics of the PMSG as a passive disturbance when designing the controller and compensates it.

Multiple Lyapunov functions and other analysis tools for switched and hybrid systems
TL;DR: Bendixson's theorem is extended to the case of Lipschitz continuous vector fields, allowing limit cycle analysis of a class of "continuous switched" systems.

Dissipative dynamical systems part I: General theory
TL;DR: In this paper, a general theory of dissipative dynamical systems is presented, where dissipativeness is defined in terms of an inequality involving the storage function and the supply function, which is bounded from below by the available storage and from above by the required supply.

Bilateral control of teleoperators with time delay
R.J. Anderson,Mark W. Spong +1 more
TL;DR: In this paper, a control law for teleoperators is presented which overcomes the instability caused by time delay by using passivity and scattering theory, a criterion is developed which shows why existing bilateral control systems are unstable for certain environments, and why the proposed bilateral control law is stable for any environment and any time delay.

Stable adaptive teleoperation
TL;DR: In this article, a physically motivated, passivity-based formalism is used to provide energy conservation and stability guarantees in the presence of transmission delays, and an adaptive tracking controller is incorporated for the control of the remote robotic system and can be used to simplify, transform or enhance the remote dynamics perceived by the operator.
