ii) If the PID controller is used as control feedback, draw the block diagram of DC motor position control by refering to Fig.1 and write a standard mathematical equation form of PID control. (9marks)

iii) Sketch the estimation transient response of motor position, with and without tacho feedback controland explain the behaviour of the response. ( Assume Input to the system is Step Function (6marks)

(a) Figure 1 shows a diagram of position control of DC motor with angle and velocity feedback control loops. Angle reference Angle feedback Velocity feedback Drive Amplifier M Figure 1. Position control of a DC motor Tacho. i) Based on Figure 1, describe the principle of operation of DC motor position control. [3 Marks]
