Passivity-based control for flight control systems
1999 Information, Decision and Control. Data and Information Fusion Symposium, Signal Processing and Communications Symposium and Decision and Control Symposium. Proceedings (Cat. No.99EX251), 1999Presents a passivity-based control (PBC) for flight control systems considering both stabilization and tracking. The aircraft dynamics are divided into fast (short period) and slow (phugoid) motions. Control laws for each motion are designed using the PBC technique.

PASSIVITY-BASED CONTROLLER– OBSERVER FOR ROBOT MANIPULATORS
International Journal of Robotics and Automation, 2008This paper deals with the velocity-observer based controller to solve the trajectory tracking problem for rigid robot manipulators, without using the velocity measurement. A remarkable feature of this observer-controller is that it originates from energy reshaping arguments, by analogy with the passivity-based methodology to robot control.

Passivity-Based Visual Feedback Control
2015This chapter extends the results of the previous chapter to visual feedback camera control. The kinematic camera control problem is first investigated, and the control objective is proved to be achieved by using passivity. The framework is further extended to dynamic visual feedback control in the eye-in-hand configuration. There, the robot manipulator

Passivity-based control [robot dynamics]
Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002Dynamics of a robot naturally satisfy passivity whether its tool endpoint is free to move or constrained on a surface of an object or environment. This property is inherent to the fact that robot dynamics can be derived from a variational form based on the concept of Euler-Lagrange formalism.

Passivity-based control of magnetostrictive materials
SPIE Proceedings, 2007In this article, velocity and position controllers for magnetostrictive materials are designed and discussed. Magnetostrictive materials are a competitive choice for micro-positioning actuation tasks because of the large force and strain they provide. Unfortunately, they are highly nonlinear and hysteretic, which makes them difficult to control.

Passivity Based Control of Power Plants
IFAC Proceedings Volumes, 2008Abstract In this paper, we show that the state space spanned by the intensive variables such as temperature and pressure is isomorphic to that spanned by extensive variables such as the mass and energy inventories for a single component process system. Then we propose a state space model for power plants, which uses the mass and energy inventories as

Passivity-based control of synchronous motors
2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012Due to its great potential value in theory and application, nonlinear control strategies of synchronous motors (SM), especially passivity-based control (PBC) methods, have been a focus in the literature. A PBC strategy for SM with time-varying load torque to track flux and speed trajectories is proposed in this paper.

Passivity based control of drum boiler
2009 American Control Conference, 2009This paper proposes a novel state space model for the drum boilers with natural recirculation. This model uses the total mass and energy inventories of the boiler as the state variables, and has an affine structure in the control variables. A passivity based inventory controller is developed, which ensures the asymptotic stability of the closed-loop ...

Passivity-based control of synchronous generators
ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics, 2002In this paper the generated power regulation control problem of a single synchronous generator connected to an infinite bus is solved. The main objective of this work is to show how the controller design methodology known as passivity-based approach, reported by P.M. Anderson et al. (1991), can be applied in the solution of this kind of problem.

Passivity is a fundamental property of many physical systems which may be roughly defined in terms of energy dissipation and transformation. It is an inherent Input-Ouput property in the sense that it quantifies and qualifies the energy balance of a system when stimulated by external inputs to generate some output. Passivity is therefore related to the
