(b) Consider the feedback control system depicted in Figure Q6-2 which is used to determine the signal applied to the motors of each wheel on the robot to set its velocity. Controller Motor Disturbance V Desired Velocity C=98 0.5 Actual Velocity Figure 26-2 (i) Explain why such a 'closed loop' feedback control system is needed. Give examples of 'disturbances and state the impact feedback should have on them. (ii) If instead the motor was 'open loop' and the desired velocity was 5, what voltage V should be applied to the motor? Calculate the actual velocity when the Disturbance is 0 and when it is 1. (iii) For the closed loop system, find an expression for the actual velocity in terms of the desired velocity and Disturbance. (iv) Find the actual velocity when the Desired Velocity is 5, and when the Disturbance is 0 and when it is 1. Comment on the results. (v) Instead of proportional control, what would you use if you wanted no error between the unchanging actual and desired velocity, and outline why this method achieves this.
