project ideas
It would be great if u tell the level of course u r doing.I mean to say
diploma,Degree.of some other engineering course.
Since u mentioned F/B control project,I wud like to suggest you to design urself"speed control of a DC motor"..This looks a simple project,but if u start doing urself on the basis of the books u read or with the help of other informative sorces like internet and project books,then u r going to learn a lot thereby.However u can make it attractive by including some software in ur project.Like if u want a filter after the encoder signal then that filter can be designed with software.
u can choose rating of motor and then the Drive for it.
i dont know whether this helps u. please acknowledge.
