This experiment enables the students to explore set-point angular position control of a link driven by a DC motor. A proportional-derivative controller is used to achieve set-point tracking. In the following control panel Kp denotes the proportional gain and Kd denotes the derivative gain. By varying these gains you can study the effect of these gains on the position tracking response of the DC motor system. An additional control knob is provided to implement and vary an integral control gain Ki. Before starting the experiment, set the control gain knobs to their tested design values Kp=0.5056, Kd=-0.4931, and Ki=0.
