When I was in grad school I made these to explain concepts from traffic theory:

These were major efforts and I don't recommend building out anything similar while pursuing a master's. But control theory does lend itself to simulation well, so I would use jupyter notebooks to present little annotated simulations with code. Print out plots of the state space at intervals for example. I also highly recommend the graphing calculator desmos.com.
