PURPOSE: To enable stopping of integral control action from the time of switching by storing integral components at the time of switching at which integral control action is stopped in controlling states including proportional control action, integrated control action and derivative control action, and adding the stored contents to control signals in the controlling states of proportional and derivative control action from the time of switching. ;CONSTITUTION: When exclusion of integral control action is selected by a selection means (f) as proportional, integral and differential operations are performed, the results of the proportional, integral and differential operations of deviations immediately after the time of exclusion are subtracted from the results of proportional, integral and differential operations of deviations immediately before the time of exclusion, and the results of these subtractions are stored in a storage means (g). The results of the subtractions substantially represent values of integral components at that time and the stored contents are added to the results of proportional and differential operations of subsequent deviataions by a correction means (h), whereby control is performed with the integral control action stopped from when exclusion of the integral operation is selected.;COPYRIGHT: (C)1993,JPO&Japio
