So I worked with Jeff on the matlab thermal work, since I had missed a fair amount during thesis time. WE managed to finish up everything. Umm ok here goes: So I worked up the part 1 of the thermal challenge in class with Robbie. The cooling and heating of coffee was really easy. But hey, I've done tons and TONS of matlab coding this semester (aka > 200 pages of matlab codes). Any who, what happens with bang bang is lots of oscillation for the control, aka the temperature of the coffee oscillates around the desired temperature. When you code in proportional control, you have trouble reaching the desired temperature. Instead the coffee tends to be right below the desired temperature and never quite reaches the desired temp. I guess Starbucks can't use proportional control then! It is quite fun to add in a time delay for the proportional control and bang-bang control. With bang-bang you see a fair amount of overshoot. You see some overshoot with proportional control too. a...
