Question 6 An open-loop system is modelled by a transfer function, given by Undertake the following tasks: i. Sketch the form of the root locus for the closed loop control system on the s-plane. Label on your s-plane sketch the following: . Lines of natural frequency and damping • Open-loop system pole locations, i.e., when . Value of that gives a marginally stable system Pole location for an underdamped system, overdamped system and critically damped system (17 marks) ii. A three-term proportional integral and derivative (PID) controller is now introduced into the feedforward path to replace the P controller. Explain the benefits of introducing a three-term PID controller.
