Important simulink files:

slider.mdl: Simulation of Dc/Dc converter (w/swithching rules) + DC motor

nonlinear.mdl: Same but with pulse-width modulation instead of switching rules
     Must go to subdir. drive: NEDC; nedc=powerProfile(nedc); cd..
      Note that the simulation is now much faster (about 10^4 times), 
      but control performance not quite as good|!
