Abstract
PURPOSE:To remove overshooting by setting up an integration time constant to the prescribed times of a previously set value when a manipulated variable is included within a prescribed range determined by upper and lower limit values and a proprotional operation value is outside a prescribed range determined by a manual reset value, and executing integrating operation. CONSTITUTION:When a manipulated variable is included with a prescribed range determined by the upper and lower limit value of the manipulated variable and a proportional operation value is outside a prescribed range determined by a manual reset value, a previously set integration time constant is multiplied by prescribed times to execute integrating operation. Since a deviation between a set value and a process variable is reduced without fail by the integrating operation setting up it integration time constant to a large value, the deviation is not left, and when the deviation is a comparatively large, the integration time constant is increased to execute weak integrating operation, so that no overshooting is generated.
