The upper limb rehabilitation robot of end-traction type, because of complex working environment, it is very easy to collide with other objects and cause accidents. A loop-locked control algorithm for redundant upper limb rehabilitation robot is proposed in this paper and the algorithm is based on the transformation of master-slave task. It achieves the switch of the task of obstacle avoidance and...
Fault-tolerance in a virtualized networking environment (VNE) requires additional efforts to provide the survivability against failures on either virtual networks (VNs) or the underlying substrate network. In this dissertation, we design a software-defined resilient VNE using a hybrid scheme of protection and restoration, where for each VN, a set of redundant virtual routers (VRs) are reserved as...
Today's smart power networks are exposed to an increasing number of cyber-attack events due to the highly integration of information techniques. It was revealed that an attacker can significantly increase the operation cost of a power system by launching undetectable false data injection attacks. However, the attack vector is determined by solving a bi-level linear programing (LP) problem, which is...
When fault occurs in distribution network, relays of the distribution network trip and the distributed generations turn to the islanding operation mode to supply the surrounding load. So the distribution network without islanding operation part is outage. Taking this into consideration, this paper considers the restoration of distribution network without islanding operation part as a multi-objective...
