The operation condition variations, such as switching load, could cause significant transient and dynamics in an autonomous system. This paper investigates the control system performance, in particular the system behavior during dynamic periods. The control systems, in particular the diesel unit control, are presented. The simulation results have demonstrated that the power electronic converters can be used to effectively minimize the voltage fluctuations and system transient.","PeriodicalId":106054,"journal":{"name":"The Fifth International Conference on Power Electronics and Drive Systems, 2003.

The novelty of this new sensor-less structure is obtained by mixing the open-loop estimator response with the steady-state estimator one. A fuzzy adaptive system weights the two estimated speed values according to the motor operating point. The final speed value is obtained averaging the previously weighted speeds. Moreover, the open-loop estimator response is improved by means of using an adaptive fuzzy controlled filter that selects the optimised cut off frequency. The aim of this system is to obtain a moderate performance without a great computational charge. Besides, the final system is more robust against variations of the internal parameters of the motor. The results validate the entire work, not only in transient and steady state but also in the start-up.","PeriodicalId":106054,"journal":{"name":"The Fifth International Conference on Power Electronics and Drive Systems, 2003.

Hence the resonance frequency of the DVR system will change and that results in harmonic resonance in the DVR. This paper presents a detailed study on possible resonance phenomena in a DVR protecting a load with power factor correction capacitor. The study reveals that the harmonic resonance cannot be reliably prevented with the existing open-loop control of the DVR due to the lack of damping and stability margin. It is proved that the closed-loop controller consisting inner current loop and outer voltage loop can dampen out possible harmonic resonance in the DVR system by properly selecting the gain parameters of the controller.","PeriodicalId":106054,"journal":{"name":"The Fifth International Conference on Power Electronics and Drive Systems, 2003.

This calorimeter has been used to verify the accuracy of models for inverters for use in variable speed drives for domestic appliances. Verification has been undertaken at a range of switching frequencies and confirms the ability of the models to predict inverter performance without recourse to physical prototypes.","PeriodicalId":106054,"journal":{"name":"The Fifth International Conference on Power Electronics and Drive Systems, 2003.

Therefore, in order to overcome this problem, a forward converter with a complex programmable logic device (CPLD) technique added is presented herein along with a hysteresis voltage-controlled pulse width modulation (PWM) scheme and the maximum current limiting, without any analogue-to-digital converters (ADCs). Also, some protection functions are added to enhance the reliability of the proposed topology, thereby allowing this converter to be likely to approach to industrial products. The validity of the proposed topology is demonstrated via some experimental results compared with those created from the conventional topology.","PeriodicalId":106054,"journal":{"name":"The Fifth International Conference on Power Electronics and Drive Systems, 2003.
