Embodiment Construction
[0039] Such as figure 1 Shown, the present invention comprises the following steps:
[0040] A. Collect the parameters of the speed control system of the water turbine, and establish the model of the speed control system of the water turbine; p ,k i ,k d The three adjustment parameters are transformed into transient slip coefficient b t , the buffer time constant T d , acceleration time constant T n The correlation coefficient of the turbine represented by , the transfer function of FOPID after Laplace transformation is:
[0041]
[0042] In formula (1), y FOPID Indicates the electrical control signal output of the governor, T d Indicates the buffer time constant, T n Indicates the acceleration time constant, b t Represents the transient slip coefficient, S represents the pull operator (α represents the integral order, β represents the differential order, when both α and β are equal to 1, it becomes a classic PID), k p Indicates the proportional gain value, k i I...
