Use arrays with PID library

6

Would it be possible to use arrays with the constructors? I have six valves with different input, output and setpoints so I wanted to know if could do something like...

modified SetSampleTime() to allow PID::Compute() synch to external timing source

1

I modified SetSampleTime() to set the internal SampleTime variable to zero for an input argument of zero, without modifying ki or kd. This forces Compute() to generate a new output...

SetSampleTime(0) doesn't change the internal SampleTime class member

15

Passing in a value of '0' for SetSampleTime() doesn't actually do anything, as the 'if' statement is coded incorrectly. ``` void PID::SetSampleTime(int NewSampleTime) { if (NewSampleTime > 0) { double...

Delays in loop() cause erratic PID.compute() values

4

I'm using the PID Library for a balancing robot and it seems to be exhibiting strange behavior. You can view the complete code here: [https://github.com/owhite/balancing_bot/blob/master/src/balancing.ino](https://github.com/owhite/balancing_bot/blob/master/src/balancing.ino) but I believe the relevant...

update Compute() so it computes on the first call

1

This is a small change to update Comput() so that it produces a non-zero output on the first call. The issue I noticed was that the PID output after the...

Derivative Kick

8

As per your article: http://brettbeauregard.com/blog/2011/04/improving-the-beginner%E2%80%99s-pid-derivative-kick/ You've choosen to do D on input. Most modern PID controllers use D on error. I think the kick experienced when a setpoint is changed...
