In this paper, we propose a passivity monitor which evaluates stability of a system based on the concept of passivity, and a software limiter which turns the system stable if it is originally unstable. It is shown that asymptotic stability will be guaranteed for arbitrary robots with arbitrary control schemes and environments, even if their properties are unknown. The validity of the passivity ...

Maintaining sound reputation requires robust control and investigation. In this paper, we analyze a reputation mechanism that objectively maintains accurate reputation evaluation of selfish agent-based web services. In the proposed framework, web services are ranked using their reputation as result of provided feedback reflecting consumers’ satisfaction. However, selfish web services may alter ...

Maintaining a sound reputation mechanism requires a robust control and investigation. In this paper, we propose a game-theoretic analysis of a reputation mechanism that objectively maintains accurate reputation evaluation of selfish agent-based web services. In this framework, web services are ranked using their reputation as a result of provided feedback reflecting consumers’ satisfaction abou...

In bilateral telemanipulation algorithms based on enforcing time-domain passivity, internal friction in the devices poses an additional energy drain. This can severely decrease the obtainable transparency of these algorithms when high amounts of friction are present in the slave device. Based on a model of the friction, the dissipated energy can be estimated and reclaimed inside the energy bala...

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 state variables, and has an affine structure in the co...

This paper provides a new approach to decentralized failure-tolerant control using passivitybased stability conditions. A controller design method is developed to achieve both decentralized unconditional stability (a transformed passivity condition) and user-specified H2 performance. The control synthesis problem is solved by using successive semidefinite programming. The proposed method is ill...
