Development and implementation
of voltage source inverters for speed-sensorless controlled
induction motor drives
Project of the Innovation Centre NOT No ROW-III-206/2012
The aim of the project was to carry out industrial research, design and implementation
of a production series of voltage source inverters for induction motor drives operating
without speed sensor. Induction motors are sensorless controlled, using the original
method of inducion motor speed and state estimation, which so far has been
implemented in costly and complex systems with digital signal processors
(DSPs) and separate analog-to-digital converters. Innovation of the design
is the result of the use of the latest ARM processors with the CPU executing
floating point operations. These processors also feature built-in controls
peripherals necessary to control induction motors and communication with
the operator and external systems.
