Yes actually I've done that before root-locus design is part of our syllabus as such...
Thing is I wanted slower movement of the antenna and hence preferred the degree-by-degree variation to slow continuous motion. It's a mattter of preference actually
This is the (badly) designed circuit. I am getting oscillations and I know why.
The switch does not have a final "settled" position. I am unable to figure it out so any experienced MATLAB users please help!
Fig1 is a picture of Scope output. It should be at 90 degree but it oscillates due to previously mentioned problem.
