I am taking a control class right now, which I find quite interesting. I had an idea for a senior project where I'd design and build a machine that allows one to hook up a motor and it will compute the torque/voltage transfer function or the angular speed/voltage transfer function of an electromechanical system. I would design the machine to input a unit impulse voltage to the system and the machine would measure torque response or angular speed response. This response would then be fit to an equation and a computer algorithm would determine the laplace transform. The laplace transform of the unit impulse response would of course be transfer function. Has this been done? Is this too simple of a project? Too hard? Not interesting enough? Any comments?
