I dont understand integral part of PID controller. Let's assume this pseudocode from Wikipedia: previous_error = 0 integral = 0 start: error = setpoint - measured_value integral = integral + er...

I am trying to throttle a loop (which is sending messages) to a particular number of messages per second. _throttle is the number of messages per second. My initial algorithm is depicted below, bu...

I need to implement an anti-windup (output limitation) for my PID controller. Simulink is offering two options: back calculation and clamping (documentation) which seem to deliver equal results. I ...

I need to tune PI(D) gains in a system which has a quite large delay. It's a common temperature controller, but the temperature probe is far away from the heater. Some further info: the response ...

I'm currently working on a temperature controller. I have a Temperature_PID() function that returns the manipulated variable (which is the sum of the P, I, and D terms) but what do I do with this o...
