motor-speed

we have a photo camera with DC Motor and closed loop controller is equal k/s^2+s+k. first,we shoul find ZOH,then we identify the system with ARX model that na=nb=2 Here,we want to identify the Dynamic Linear System. we use different inputs such as normal distribution,uniform distribution,...
