The program described in exercise 4 is able keep a fixed distance to an object in front of the regulated device. In order to so it implements a linear feeback system in terms of a proportional only controller where the feedback is the measured distance to the object. By subtracting the measured distance from the setpoint and multipliyng this by a Pgain factor the program will make the car drive fast when it is far away from the object and decreasing the speed as it gets closer to the object.

The variables in the system is as follows

|
|
|
|
* Setpoint variable (SP) = **desiredDistance**
|
|
|
* Process variable (PV) = **distance**
|
|
|
* Manipulated variable (MV) = **power** |
