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 5V. The table below shows the actual output values for each loop of the controller program. The table: In the left hand column - Time (ms): 0, 49.9, 99.8, 149.7. In the right hand column - Speed (V): 0, 0.85, 2.9, 4.05. If the controller has settings of Kp = 2.59, Ki = 0.00208, Kd = 6 (with all units defined in time units of ms), what is the current output value of the PID controller in V?
Answer = 3.28V. Please show each step with numerical working and check that the value you obtain is actually 3.28V. I am yet to see anyone get this correct. Thank you.
