DC Motor Position: PID Controller Design Using the Root Locus Approach 1.Physical Setup: A common actuator in control systems is the DC motor. It directly provides rotary motion and, coupled with wheels or drums and cables, can provide translational motion. The electric equivalent circuit of the armature and the free-body diagram of the rotor are […]
