摘要: In a process control system prior to execution of control, manipulated variable which an identification signal from generator is added inputted process. preadaptation section, controlled output the sampled obtain its dead time and maxmum gradient, initial values PID parameters are calculated on basis maximum gradient. The like set in adaptation section. pulse transfer function acquired, acquired by using partial matching method frequency region. After these executed.
