Abstract

PURPOSE:To perform the integral feedback operation and the deviation feedback operation, by setting a reset bias value and operating this value, an operation output limit value, a proportional gain, and a deviation in the process control device with a reset limiter. CONSTITUTION:A control operation part 1 integrates an output Kpe (Kp is a proportional gain) of a proportional operation element P by an integral operation element I and adds and integral term B of the output and the output Kpe to generate a PI operation output YV. This output YV is inputted to an output limiter 2; and when the YV value exceeds a control value LM of the limiter 2, an operation output MV is controlled to LM, and a changeover switch 5 is switched. At this time, an output FV=reset bias set value RB+MV-Kpe from an adder and subtractor 4 is inputted to the element I, and a value determined with a certain time constant by the output FV is set to the integral term B again. In this case, if RB is set to 0, the integral value is set to LM-Kpes (es is an offset) finally, and integral feedback operation is performed. If RB is set to Kpes, the deviation feedback operation is performed.
