Title:
LOAD DECENTRALIZING SYSTEM OF MULTI-LOOP CONTROLLER
Document Type and Number:
Japanese Patent JPS59127111
Kind Code:
A
Abstract:
PURPOSE:To decentralize the control execution timing to plural control loops and to equalize the load by performing the control in the sampling cycle ISI at an initial start time point and then using the sampling cycle SI thereafter. CONSTITUTION:At the time of an initial start, the cycle SI-ISI is calculated from the sampling cycle SI stored in a table 2 and the sampling cycle ISI stored in a table 2' and then set to a table 3. The cycle SI-ISI is set to the table 3 for measurement at the time of the initial start. Therefore 4, 3, 2, 1 and 9 are set to the 1st, 2nd, 3rd, 4th and 5th loops (1), (2), (3), (4) and (5) respectively. Thus the 1st loop is controlled in a cycle t1, and hereafter the control is continued in the cycle SI. In the same way, the control is carried out with the 2nd and follow loops. Thus the control is decentralized.
