Te Ziegler- Nichols metodic is a popular technique user to tune proportional- integrative (PID) controllers. It provides a systematic way to determinate controller parametrs based on he system 's response. This methode enterves identififying specific system charakteristics s prompgh experiments and calculations.

Understanding thee Ziegler- Nichols Methodd

To je to, co se děje, když se to děje.

Krok po kalkulaci Controller Parameters

Follow these steps to determinate thee controller parameters:

  • Set the controller gain to a low value and gradually increase it until then system output disputs sustainabled oscillations.
  • Record thee gain value at this point as Ku.
  • Měření period o f these oscillations as Pu.
  • Use the Ku and Pu values in the Ziegler- Nichols formulas to calculate PID parameters.

Parameters

Te Ziegler- Nichols tuning rules providee thee following formulas:

  • CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; Proportional gain (Kp): CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3CCANE3CCADE3; Proportional gain (Kp): CLANE1; CLANE1CLANE1CLANE3; CLANE3CLANE3; 0, 6 × Ku
  • CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; Integrální time (Ti): CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; 0.5 × Pu
  • CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; DERVAtive time (Td): CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; 0.125 × Pu

Application and Adjustment

After calculating the initial parametrs, implementt them in the controller. Observe thee system response and make settings if necessary. Fine- tuning may be impord to optime performance for specic applications.
