Q: LIXISE generator excitation control PID adjustment and its algorithm?

a: LIXISE generator Excitation control The PID and its algorithmIn the excitation control system, the applied voltage deviation PID regulation can be achieved:

1) steady-state greater magnification, the voltage of the machine is close to a constant, adjustment precision is within 0.1%, and thus have larger small signal stability limit;

2) transient sometimes smaller magnification, in order to avoid overshoot and oscillations.

According to the deviation of proportion, integral and differential control the excitation control of PID regulator, is a continuous system of excitation control of a mature technology, the most widely used one kind of the excitation control regulator.

Excitation control proportional control can reduce the inertial time constant control system, but the relative stability is reduced, and can not eliminate the steady-state error;Integral regulation can eliminate the steady-state error;Differential regulation can improve the stability of the control of excitation control, can increase the proportion of corresponding adjust magnification.
