Abstract

PURPOSE:To prevent overshoot and undershoot and to increase the controllability against external disturbance, by providing a compensation from a deviation to a split devition operation and controlling an on-line regulating valve which makes regulating operations such as proportional + integral + differential operations. CONSTITUTION:A temperature in a room 22 is actually mesured by a temperature detector 31 and the result is applied to a subtractor 30. The subtractor 30 subtracts the actually measured temperature value from a set temperature SV to obtain a deviation of both polarity (+ or - e). The positive deviation (+ e) is fed to a succeeding signal split operator 32 for the operation to increase a process variable, and an output IA is applied to multiplier 36. The output IA and an output IC of an operator 34 are multiplied 36, and an obtained deviation operating output IE is applied to a hot brine temperature regulator 38, which makes a regulating operation such as proportional + integral + differential operation, and the output signal controls an on-line regulating valve 24. Further, the negative deviation (-e) is fed to a succeeding signal split operator 33. Similarly, the output is given to a cold brine temperature regulator 39, where the cold brine regulation 27 can be made.
