Consider the design of a speed controlled DC motor, with proportional feedback control. The armature's applied voltage to current transfer function is given by: Ga (s)- The torque constant maybe assumed to be unity. The mechanical transfer function relating the torque input to motor speed output is, 1 0.05s +0.1 1 Ga (s) - 0.1s +1 It is required that the peak time be less than 0.5 seconds and the percent overshoot is less than 5%. An appropriate proportional feedback gain constant K that meets these requirements is given by:
