Field oriented vector control is unsuitable for this operation due to coupling, non-linearities and saturation of linear current controllers. Proposed Direct Flux Control scheme does not use current controllers to achieve dynamic torque control. Vector control of the stator flux vector allows for dynamic change in torque in all regions, including field weakening with six-step operation. This paper describes the dynamic torque control by using stator flux vector magnitude change and it's angular velocity. Such control is carried out by using fixed switching frequency dead-beat control of stator flux. The method is demonstrated experimentally.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

In order to optimise the customized IPM to an elevator system, we simulated and measured the spike voltage and the motor surge voltage including the temperature variation due to the switching losses at the IPM case and heat-sink. As a result, thanks to the optimised value of the gate resistor to the IPM, the conducted EMI noise is reduced approx. 5/spl sim/10 [dB/spl mu/V] in a particular frequency domain.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

In ATM a traffic-shaping buffer is used to prevent excessive back-to-back cells being generated during the peak transmissions of Moving Picture Expert Group (MPEG) variable bit rate (VBR) data sources. The VBR data sources are unpredictable and have substantial variations in bit rate, which could result in data loss and therefore image quality degradation. In this research, a self-organizing fuzzy controller is applied to digital video to eliminate excessive delay or loss at the user network interface. A self-organizing fuzzy controller adjusts the traffic-shaping buffer output rate frame by frame to enable the VBR encoded video to conform to the leaky bucket's contract. A rule-based fuzzy (RBF) controller regulates the average arrival rate to the traffic-shaping buffer to prevent either overflow or starvation of the buffer on a group of picture (GOP) by GOP basis. The computer simulation results demonstrate that the use of a SOF controller reduces excessive delay and data loss at the user network interface as compared with a conventional policing mechanism in ATM.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

Therefore, the rules that allow the exchange of messages, i.e. message scheduling policy, is a key issue in terms of system performance. For control applications where control loops are closed over communication networks, this is especially true. Traditional scheduling policies are based on models and techniques that do not take application demands into account. This precludes the dynamic adaptation of the use of the communication bandwidth according to the application needs. To overcome this problem and focusing on control applications, we present an early specification of a novel scheduling technique: large error first (LEF). This scheduling algorithm uses feedback information from the application in order to assign communication bandwidth to each individual component. We studied the performance of a distributed application when the messages are sent according to this novel scheduling policy and encouraging simulation results have been obtained.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

In this paper, a MOS-controlled diode (MCD) for power integrated circuits is presented. The proposed structure utilizes active control to switch the diode between unipolar and bipolar operating modes so that the device can operate at its optimum condition for both static and dynamic performances. The proposed MCD on SOI demonstrated significant advantage over a P-i-N diode or the body diode of an LDMOS. It is found that, with optimum control, it can reduce the diode reverse recovery loss by 10 times and the corresponding switch turn-on loss by a factor of 3, without sacrificing its on-state conduction voltage. The traditional trade-off between on-state voltage and reverse recovery speed can therefore be avoided and significant improvements in overall system efficiency can be achieved. Advantages of an integrated MCD over its discrete version are also discussed.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.
