The application discloses a PID anti-integral saturation method,
system, device and medium for an Ovation
control system, and the method comprises the following steps: a
TRANSFER function block is arranged between the output end of a
PID controller and an
actuator; a real-
time limit value
signal is acquired, and the real-
time limit value
signal comprises an upper limit
signal value and a
lower limit signal value; the output signal of the
PID controller is compared with the real-
time limit value signal, and the
TRANSFER function block is triggered according to the comparison result; and the output value of the
TRANSFER function block is reversely transmitted to the
PID controller through a tracking line by using a preset configuration tracking function, so as to reset the internal operation result of the PID controller. By adding the TRANSFER function block at the output end of the PID controller and introducing the real-time
limit value signal which dynamically changes with the working condition, the technical limitation that the internal limiting parameter of the PID module of the Ovation
system cannot be introduced and cannot follow in real time is solved.
