I had the privilege of taking the beta version of this intense three-week introduction to control theory. It's a hands-on experience that covers the basics of control -- i.e., keeping a system operating at a desired setpoint using feedforward and feedback strategies. The course takes a discrete-time approach to avoid differential equations, but the math is still far from trivial, and discrete time is what today's digital controllers use. The first week builds the necessary mathematical foundation of sequences, difference equations and natural frequencies. The second and third weeks get into the meat of control theory, culminating with an exploration of Proportional plus Sum plus Delta (PSD) feedback, the discrete-time equivalent of the well-known Proportional plus Integral plus Derivative (PID) feedback paradigm. Students (reversibly) harvest a propeller arm from an inexpensive drone and combine it with an Arduino controller to create a programmable control system. A series of excellent user interfaces allows you to vary different control parameters and see the effects on the propeller -- does it hold steady, does it oscillate, or does it fly out of control? A terrific simulator ties the math directly to its control effects, allowing you to enter a difference equation and see how well controls an animated helicopter as it changes height. There were no lecture videos in the beta course, but the written materials were so good that I wonder whether lectures are even necessary, and the professors, Jacob White and Joe Steinmeyer, were incredibly dedicated -- fielding innumerable questions, fixing minor glitches, and taking a heroic interest in students' progress and understanding. It's amazing how much we covered in three weeks, though when it was over, many of us were eager for more -- and hopefully, down the road, there will be more.
