| description | The invention relates to the technical field of industrial process control, in particular to an optimal parameter acquisition method of a proportional-integral controller. The optimal parameter acquisition method of a proportional integral controller specifically comprises the following steps: S1, establishing a transfer function of a black box process Z-N model; S2, establishing a transfer function of a PI controller; S3, establishing an open-loop system frequency domain function of the PI controller and the black box process Z-N model according to the transfer function of the black box process Z-N model and the transfer function of the PI controller; S4, setting a transfer function of the PI controller and a preset parameter of a frequency domain function of the open-loop system; and S5,searching the optimal parameters of the PI controller. According to the method, the black box process Z-N model is engineering modeling of the black box process, no complex intermediate process exists, the optimal parameters |
