In this paper fuzzy speed and current controllers are proposed for closed loop speed control of a converter fed dc motor drive. The performance of the fuzzy controlled system is compared with that of P-I controlled system to establish its suitability. The controller is implemented in a 486 based PC, and attempt is made to control the motor from a remote operating point via FM transmitter and re...

In this paper, a harmonic elimination and suppression scheme for a dual-inverter-fed open-end winding induction motor drive is presented. Two isolated dc-link sources with voltage ratio of approximately 1 : 0.366 are required for the present drive. These two isolated dc links feeding two inverters to drive the openend winding induction motor eliminate the triplen harmonic currents from the moto...

The concept of this work helps to develop a switched reluctance motor (SRM) drive. Because of salient feature like four quadrant, rigid structure, high-speed capability and low cost from other types of motors, switched reluctance motor is more predictable in high speed applications. Its on-board integrated charger is formed using the embedded motor drive components. Good driving and regenerativ...

The electronic inverters normally operate in a current controlled mode. Current controllers are prone to errors associated with nonlinearity and offsets in the current transducers. Their successful operation requires measurement of the instantaneous values of stator currents. Using the switching signals and dc link current, this paper presents a new algorithm for the reconstruction of stator cu...

This paper presents an integrated power factor correction (PFC) buck-boost buck converter based voltage source inverter (VSI) fed brushless DC motor (BLDC) drive using a single voltage sensor. The speed is controlled by controlling the DC bus voltage of the VSI. An electronic commutation of the BLDC motor is used which utilizes a fundamental frequency switching (FFS) of VSI which in-turn offers...

The development of high performance variable speed brushless dc motor drive is very important in all industrial applications. Generally, a high performance BLDC motor drive system must have good dynamic speed response, reference speed command tracking capability and load regulating response. Conventional controller such as PI, PID does not provide good dynamic response due to the problem of non...
