Digital Motor Control Overview<br />
TMS320C2000 digital signal controllers<br />
reduce the overall cost of motor control<br />
systems by providing the integration and<br />
performance necessary to implement<br />
advanced control techniques such as<br />
sensor-less vector control of three-phase<br />
motors. Using the more processorintensive<br />
sinusoidal control, for example,<br />
allows developers to reduce the size and<br />
cost of the motors and power electronics<br />
required to meet their needs. To fully<br />
capitalize on the capabilities of the latest<br />
advancements in motor designs and control<br />
techniques, engineers are turning their<br />
focus to C2000 digital signal controllers.<br />
TI provides a free library of motor control<br />
software systems that are tailored to various<br />
control techniques and motor types.<br />
Each of these systems is a complete<br />
project developed for the Code Composer<br />
Studio Integrated Development<br />
Environment. Each is built upon our foundational<br />
motor control library software<br />
modules and includes complete documentation<br />
with step-by-step instructions<br />
to guide engineers through the process of<br />
bringing up a motor control system. Each<br />
system comes with complete C/C++<br />
source code.<br />
