Matrix converter-driven AC motor drives

2019
The matrix converter (MC) is an AC-AC power converter topology. The MC topologies are classified into two types: direct MC (DMC) and the indirect MC (IMC) [I]. The IMC topology is composed of a rectifier with six bidirectional switches (BDSs) and a conventional voltage source inverter (VSI).

Fuzzy controller in AC servo motor drive

Seventh International Conference on Electrical Machines and Drives, 1995
This paper presents the use of fuzzy control in AC servomotor drive applications. Comparison of performances obtained with an usual proportional integral (PI) controller and a fuzzy controller in both current and speed loops are presented. Simulation with the Matlab simulink package permits a comparison of the obtained responses to a reference step ...

Sequential control by speed drive for ac motor

AIP Conference Proceedings, 2012
The speed drive for ac motor is widely used in the industrial field to allow direct control for the speed and torque without any feedback from the motor shaft. By using the ABB ACS800 speed drive unit, the speed and torque can be controlled using sequential control method.

Hardware in the loop for failure analysis in AC motor drives

2016 ELEKTRO, 2016
The paper deals with an extensive experimental analysis of failures in ac motor drives exploiting a Hardware In the Loop (HIL) implementation. As many types of faults lead to stop the drive operation, a suitable approach for the realization of an appropriate test bench consists in the replacement of some hardware with an embedded system based on a FPGA

Parameter Sensitivity In Vector Controlled Ac Motor Drives

SPIE Proceedings, 1987
The relatively recent development of the theory of vector control has enabled ac machines to be transformed, performance wise, into equivalent separately excited dc machines while retaining the many advantages that ac machines have over dc. The ac machines used include the induction and permanent magnet synchronous motors.

Three-Phase Z-Source AC-AC Converter for Motor Drives

2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006
This paper presents a Z-source ac-ac converter system and control for general-purpose motor drives. The Z-source ac-ac converter system employs a unique LC network to suppress the over-current and surge voltage due to the shoot-through or the open-circuit of the two switches.

Literature survey of permanent magnet AC motors and drives

Conference Record of the IEEE Industry Applications Society Annual Meeting, 2003
The authors survey the literature on permanent magnet (PM) motors and drives and include line-start as well as inverter-fed applications and designs. The literature on inverter-fed applications and designs is divided into two parts: studies that deal with drives that use discrete feedback every 60 degrees (electrical) for a three-phase machine, and ...

The Economics for Selection of Drives---AC Motors or Steam Turbine Mechanical Drives

IEEE Transactions on Industry Applications, 1985
Applying mechanical-drive turbines is an option when the opportunity exists for cogeneration. Conversely, new developments in the technology of variable-speed ac drives have enhanced motor application for drive systems when a wide range of speed control is required.
