Trick of the month : Linear process?
A process is linear when it behaves identically independently of the type of signal sent to the final element.
For example, is the response identical for :
- Small and large changes?
- Increasing and decreasing?
- Small and high flows?
- Low and high loads?
- Slow and fast changes?
- Simple and multiple changes?
- etc.
If one of the answer is no, the system is non linear. It is essential to verify linearity before tuning a loop.
If non linear, it should be modified repairing final element (stiction, hysteresis, asymmetry, inherent characteristic, positionner), modifying control strategy, modifying characterizer (input or output) or modifying process.
If the system is still non linear, tuning parameters must be calculated using the worst case to ensure the system is always stable (and meets selected tuning criterion).
