Abstract

PURPOSE:To control a process stably by knowing the synamic characteristics of the process by using a fine identification signal during closed loop control. CONSTITUTION:The output signal U'*(t) of a sampled-value PID control arithmetic part 5 and the identification-signal V'*(t) of an identification-signal generation part 7 are added 6 together and the output signal U*(t) is inutted to a sample holding part 2 to obtain a process operation signal U(t). With a sample process signal Y*(t) obtained through a sampler 8 from the output signal U*(t) of the addition part 6 and a process signal Y(t), a sampled-value PID control constant, an integral constant and a differential constant are operated. This operation is performed by a pulse transfer function identification part 9, a transfer function arithmetic part 10 and a sampled-value control constant arithmetic part 11. This control constant is inoutted to the arithmetic part 5.
