s can outcome in you upgrading a controller to a fashionable prototype or vendor, duplicate the exact P,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych], I and D constants over,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych], and be left with a totally out-of-control process. This is because you live in a earth where always contractors implement the PID control algorithm with different degrees of functionality.
This means that it namely important to identify and know what controller type you are tuning. The differences that we absence to understand, because they ambition influence the tuning,[link widoczny dla zalogowanych], are:
1. Algorithm Type: Ideal, Series or Parallel
2. Proportional Units = Gain alternatively Percentage
3. Integral Units: seconds per repeat,[link widoczny dla zalogowanych], repeats per second, minutes per repeat or repeats per minute
Derivative Units: seconds or minutes
That manner namely there are 3 * 2 * 4 * 2 = by fewest 48 assorted medleys of algorithms and units that anyone single master tin implement.What are the odds that the controller you are using uses the same units and algorithms as the fellow who wrote the tuning means you are using? Less than landing Zero aboard a roulette chart!
This means that you must know:
? which of the 3 Algorithms your tuning rules are designed for
? and which particular units it gives you the answers in
It is then essential that you convert the tuning constants so they are compatible with your algorithm and your units.
A nice PID Tuning technique will walk you step-by-step through:
? How to ascertain out the exact algorithm your controller uses.
? How apt become your calculated P I and D constants apt your controller’s characteristic units.
? How to convert your constants to the units that your controller uses.
