Fig.2. Block diagram of Continuous PID Controller What the PID controller does is basically is to act on the variable to be manipulated through a proper combination of the three control actions that is the P control action‚ I control action and D control action. The P action is the control action that is proportional to the actuating error signal‚ which is the difference between the input and the feedback signal. The I action is the control action which is proportional to the integral of the actuating

Function Functions are basically the exact same as subroutines‚ except that they return a value. That means that the function itself has a type‚ and the function will return a value to the calling subroutine based on the code that it contains. An example of this would be a function that adds two numbers‚ shown below. A function is declared the exact same way as a subroutine‚ except using the "Function" keyword instead of "Sub". To return a value‚ assign a value of the proper type to the function’s
