摘要
The process control system has a feedback controller and at least one manipulation variable and one control variable. The feed forward loop includes an easy to receive system. Independent feedforward control is incorporated into the feedback controller including the following steps. The feed-forward control funnel and the feedback control funnel calculate the time (TFF) And the time at which the control variable reaches the normal value (TFB), Respectively. A shorter feedforward control funnel and feedback control funnel are selected. TFFTFBThe feedback control speed is corrected so as not to increase the feedback controller speed. TFFTFBIf greater than or equal to, no correction is performed and efficiently provide independent adjustment parameters for the feedforward control solution and the feedback control solution. A new value of the control variable cv is calculated and the processing is controlled by this newly calculated cv.
