V/f control strategy for permanent magnet synchronous motors can be useful for HVAC applications, where not high performance is required. Permanent magnet synchronous motors have efficiency advantages over the induction motor. But open loop V/f control is not stable in the whole frequency range. As demonstrated, the V/f control strategy becomes
Article
When permanent-magnet synchronous motors (PMSMs) are used for pump and fan applications, V/f control methods can be used to control them. The problem with open-loop V/f control of PMSMs without having damper windings in the rotor is the inherent instability after exceeding a certain applied frequency. In this paper, a new V/f control method is prop...

Conference Paper
Three models were evaluated as possible “basic” level IGBT models, and none were found to be satisfactory. Specific goals for simple parameter extraction are proposed as the primary criteria in the development of basic IGBT models. A new basic model was developed which offers promising results. Performance can be improved with additional parameter...

Project
The objective of this project is to look at simple as well advanced control techniques for IPMSMs. A prototype micro-controller based controller incorporating a Voltage Source Inverter and suitable sensors will be developed in the laboratory.
Project
To design and implement of a power flow control system for a three-phase three-level multilevel converter connected to the grid. The input to the multilevel converter is an energy storage connected with an renewable energy source.
