It is well-known that the transient response of stepping motors is generally oscillatory in the case of open-loop control. The rotor oscillation must be suppressed in quick positioning applications. In this paper, the suppression control of the rotor oscillation of VR (variable reluctance)-type stepping motors is studied. The suppression control is achieved by the inverse-phase excitation damping using fuzzy reasoning. The availability of the proposed control is shown by numerical simulations and experiments.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

However, this advantage cannot be obtained in the reaching phase. The remedial approach adopted here is that a small switching surface slope is used at the beginning and then it is increased continuously when the system output approaches the reference setting. This method reduces the duration of the reaching phase and hence the sensitivity to disturbances during the early control period. Simulation of a brushless DC motor velocity regulator system to illustrate the effectiveness of the approach is included in this paper.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

Firstly, a significant air gap between the base of the vehicle and the roadway must exist for practical operation and secondly, the tolerance to lateral displacement must be extremely high. This paper describes the adaptation of an IPT technique used for electrified monorail systems to a roadway powered electric vehicle. A prototype vehicle has been constructed and tested on a 200 m track. An average power transfer of 1.2 kW has been achieved with a lateral displacement tolerance of /spl plusmn/400 mm and a vertical clearance of 75 mm.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

A variety of ICs operating from 3.3 V are available. Next generations of ICs are expected to work even with lower voltages, i.e., in the 1-3 V range, to further enhance their speed-power performance. At the same time, during transients these new generations of data ICs will present very dynamic loads with high current slew rates. As a result, they will require point-of-load power supplies in order to minimize the effects of the interconnection parasitics. These on-board power supplies will be derived from the existing voltages available in the system (usually 5 V or 12 V), and will be required to have high power densities, high efficiencies, and good transient performance. This paper presents design considerations for these on-board power supplies and discusses their performance limits imposed by various circuit and system parasitics.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

Therefore, the performance of the inner current loop control of large voltage source power converters is studied with respect to the ability to limit converter current during disturbances in the supplying AC network. The disturbance here studied is the impact of a phase shift in the AC bus voltage which can occur at line disconnection(s). A comparison is made between inner current loop implementation in either the /spl alpha//spl beta/-plane or the rotating dq-plane. The influences of an extra time delay introduced using digital control and the sample period (pulse number) are also evaluated. Results are presented from dynamical studies, using both digital simulations and real time analog simulations with a digital control system. The simulations verify that the ability of the implemented inner current loop to limit the power converter current during a phase shift in the line voltage is highly dependent on the chosen sample period (i.e. switching frequency).<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

A simple analysis and design procedure is used for designing the converter for low line current harmonic distortion and high power-factor (PF) operation. The converter performance characterstics have been verified with SPICE simulations and an experimental prototype SPRC, without using active control. These results show that, although no active control is used, the converter operates with a line current total harmonic distortion (THD) of <15% at full load and 23% at 10% load, with line PF >0.975. Active control has also been implemented with the experimental prototype to achieve a line PF >0.99 at full load and a THD of <15%, for the entire load range.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The torque control strategy needs accurate position and speed information, but the BLDC motor has a low resolution internal encoder to determine switching position. Therefore, the speed and the intermediate position are obtained from a stable estimator which would be derived from nonlinear modelling. The torque control algorithm is derived for a motor of arbitrary back-EMF waveform considering the freewheeling current. It would be possible to have accurate speed control for wide range of speed without torque ripple. The proposed system is easily implemented and computation time is reduced by new motor modelling. In the experiment, the controller is realized by a DSP TMS320C31. The effectiveness of the controller is shown by simulation and experiment.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.
