Connecting these loads to power supply systems without this transformer is very difficult because of feedback problems, like distortions of the electrical currents and a decrease of the output voltage at the end of the feed line. In this paper, a scheme is presented which converts a large single-phase R-L load into a balanced three-phase load and eliminates the use of a transformer.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The method is based on feedback information obtained by estimating the distance from the present state to the switching surface along the optimal trajectory. A fuzzy algorithm is used for the implementation of the control logic. The advantages of the proposed method over the traditional bang-bang control method are illustrated by numerical simulations of a servomotor system.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The key of the proposed model is to take into account the armature reaction and magnet demagnetization, hence the shift of operating point at load conditions can be considered. Making use of this model, the PSpice simulation of a typical PM DC motor drive is performed. Apart from the steady-state simulation, transient behaviours of the PM DC motor drive, including start-up, sudden load change and sudden reference change conditions, have been simulated conveniently. Based on a low-cost circuit simulator-PSpice, the developed model is especially helpful for undergraduate students.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The induction motor is controlled to operate in constant flux mode. The scaling factors of input to the controller and output are altered to modify the speed response. For obtaining better steady state response, nested control windows of a lookup table are used. The results show that the response with this controller is superior to the response with a PI controller especially when the motor is loaded or the load is altered.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

Due to the equivalent series resistance of the electrolytic capacitor, the capacitor current causes a power loss which increases its temperature and may shorten its life time. It is important therefore to estimate the effective value of the capacitor current accurately. This paper presents a detailed analysis of the ripple current of an electrolytic capacitor in a boost-type power factor control circuit. The ripple current is divided into two components, namely the low-frequency and the high-frequency components. The root-mean-square value of the capacitor current is derived for both components. The analytical results are confirmed by experiments.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The controllers so designed based on the nonlinear control techniques are applied to a VR motor model (taking saturation into account) with the aim of improving dynamic performance as well as reducing torque and hence speed ripples. Test results obtained through digital simulations show improvements in torque and speed ripples over the conventional proportional-integral (PI) controller. Finally, a hybrid controller is designed by using both the feedback linearization and fuzzy tracking control algorithms. Simulation test results obtained front the hybrid controller show further improvements in reducing torque and speed ripples over the fuzzy as well as feedback linearization controllers.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

Walking simulations with the IWR model are shown using the proposed ZMP control method.
