The PID controller is widely employed because it is simple, efficient and effective. The PID gains can be designed based upon the system parameters if they can be achieved or estimated precisely. Mat Lab is often used for modelling and simulation of control systems. Task 1.0 The aim of this assignment is to investigate a PID controller for a DC motor modelled in

Fig 2.0Fig 3.0 •the use of Bode-plot to analyse the stability of the DC motor system in Fig 1.0 and justification of the result using Routh-Hurwitz stability criterion. •investigation of the step input response of a PID controllers in terms of position control, tracking and disturbance rejection for dc motor system in Fig 1.0.
