The TU consists of a rotational actuator and a wheel, which is connected to the shaft of the actuator. The TU can be attached to any position on the beam as an additional actuator, and its counter-torque controls the beam's vibration. In order to show advantages of the TU for control of a flexible beam, we carried out some computer simulations of PD control for the flexible beam with the TU and without it. It was clarified from the simulation results that using the TU as an additional actuator improves control performance and saves energy. Moreover, it was shown how the TU's wheel size and position affect the control performance.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

A disturbance compensation problem is solved by a fuzzy logic system (FLS) with adaptive positions of output fuzzy membership functions. The stability of the adaptation procedure is given via the Lyapunov stability theorem. FLS is divided into three fuzzy subsystems according to the physical properties of robot dynamics. This structure results in a clear fuzzy rule base with a reduced number of rules and enables systematic inclusion of linguistic knowledge. Performance of the proposed method is illustrated by experimental results in a motion control task and positioning task with varying payload on a three degree of freedom direct drive robot.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

It is based on a single-ended primary inductance converter (SEPIC) operating in the discontinuous conduction mode. In this operation mode, it approximates a voltage follower and the line current follows the line voltage waveform to a certain extent. The reduction in low-order harmonics and improved displacement power factor is achieved without the use of any voltage or current sensors. The simplicity and reduced parts count of the proposed topology make it an attractive low-cost choice for many variable speed drive applications.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

Therefore the effective Internet service provisioning completely depends on the reliability of VP server layer network from the perspective of the optimality and the network survivability. This paper proposes the distributed ATM VP PVC restoration framework with the dynamic rerouting schemes in hierarchical transport network. The rerouting algorithm aims to provide rapid ATM VP PVC restoration in the case of fault or performance degradation in terms of maximization of network resource utilization and satisfaction of the end user's QoS requirement. It guarantees the IP network survivability in spite of ATM network faults or performance degradations. In addition, this paper evaluates the rerouting performance for a real network, the High Speed Information Network (HSIN).","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

A new and promising use of networks is in the area of high performance control and automation, which is developing into attractive and widespread applications. Some of the major concerns in using networks to perform remote network-based control are QoS issues such as time delay and bandwidth constraints. Disturbances and unanticipated events often happen to network-based applications. When anomalies happen, if the network cannot provide the required QoS, the application may have to lower its performance requirement and use the assigned QoS to do the best as it can to maintain the application availability. This paper proposes the use of real-time application gain adaptation to compensate for QoS variations and deterioration. A numerical and an experimental simulation of a network-based controlled DC motor are used in this paper to illustrate the effectiveness of the proposed scheme.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

However, power electronic loads, when tightly regulated, sink constant power from the system. Therefore, they have negative incremental impedance characteristic.

In this paper, these loads are modelled using the generalized state space averaging method.
