In this paper we propose a novel approach to deal with synchronization of networked Euler-Lagrange systems separating local controller design from topology graphs. A specified consensus network is first constructed, where many existing consensus algorithms regardless of our node dynamics can be used. Subsequently, each Euler-Lagrange system is driven by a local controller designed together with the...
In this paper, the cooperative control problem of networked Euler-Lagrange systems with parametric uncertainties and unidirectional interaction is addressed under dynamically changing topology. As the communication graph evolves over time, a distributed control law via local effective interactions is designed. Adaptive techniques are used to deal with parametric uncertainties in the dynamics. With...
Orthogonal Frequency Division Multiplexing (OFDM) is a promising technology for combating the frequency selective fading, multipath propagation, and narrowband interference in power line communication. However, OFDM systems are extremely sensitive to synchronization deviation. Slight synchronization deviation can affect the performance of OFDM systems. This paper presents a design and implementation...
Workflow management systems (WFMS) facilitate the routine operation of business processes and gain popularity in recent years. To ensure the correctness of business process specification and execution, model verification (especially structure verification) must be conducted so that we can identify any violations and consequently take proper action to remove them in time. However, little progress has...
