No one I talk to today will give a shit about this, so I will post it here. Today I programmed a proportional feedback loop to control the pressure build rate of a hydraulic piston from the travel rate of an electronic actuator given dubious initial conditions. (electric autonomous brake applier controlled via CAN) A good place to end a Friday. Remember, if anyone tells you that you will never need math, you hit them right in the face. Time for a beer!
