Digital controllers find applications in power electronics, industrial drives, automotive, motor control, etc. This course has been designed with both theory and hands-on lab sessions. The lab component focuses on the programming of TI DSP in particular using CCS IDE followed by digital controller concepts in the theory sessions. An overview of F28379D, SysConfig, SFRA features and examples specific to power applications will be introduced in this course.
The lab sessions are organized such that participants can learn the concepts and would be helpful to design a system control. This course has been offered at IIT Madras for 7 years and the course material has been formulated as required.
Hence, this course will be helpful for students pursuing a career in Electrical and Electronics Engineering.
In this course, additional sessions are organized by Texas Instruments and MathWorks to give a brief overview on the architecture and embedded coder.
