Claims

[Scope of utility model registration request]

In a process control device that controls the flow rates of at least two types of process fluids, a primary regulator inputs a process variable and outputs a set value, and a ratio of the flow rates of the two types of process fluids is set to generate a specific output. a ratio setter, a first calculator that inputs and calculates the output of the primary regulator and the output of the ratio setter and outputs a set value; a second computing unit that inputs and calculates a set value output and outputs the set value; and a first secondary flow rate controller that receives the set value output of the first computing unit and controls the flow rate of one of the process fluids. and a second secondary flow rate regulator that controls the flow rate of the other process fluid by inputting the set value output of the second computing unit, and operations of the first and second secondary flow rate regulators. A process control device comprising a tracking computing unit group that controls the primary regulator and the ratio setter depending on the state.
