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.
If the controller has settings of K_(p)=2.76,K_(1)=0.00263 and K_(d)=7.07 (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.

The correct answer is:
3.63 [5 marks, 2 decimal places otherwise 4.0 marks]
