A discrete PID controller is used to set the speed of a motor. The set point for the motor, as measured by the speed sensor, is 5 V. The table below shows the actual output values for each loop of the controller program. Time (ms) Speed (V) 0 0 38.10 0.71 76.20 2.65 114.30 4.18 If the controller has settings of Kp = 1.73, K = 0.00164 and Kd = 7.21 (with all units defined in time units of ms), what is the current output value of the PID controller. Give your answer in V to 2 decimal places. Round your answer to 2 decimal places. Score: 0/5 Unanswered Advice The correct answer is: 1.73 [5 marks, 2 decimal places otherwise 4.0 marks] You get a mark of O for an incorrect answer. Maximum mark is 5 for this question. See Bolton section 22.7.3 for more details on this topic. When calculating the integral term, be sure to sum up all previous error contributions. Score: 0/5
