Abstract

PURPOSE: To reduce the effect of disturbance, by determining a command for a conventional follow-up control system by a predictor to which the disturbance and the difference between the command and a measured value of the control system.
CONSTITUTION: A block 10 surrounded by the dotted line in Fig. is the conventional follow-up control system, which consists of a comparator 13, a PID calculator 14 and a controlled object 11 and receives the disturbance 15. The command for the control system is determined by the predictor 22, a coefficient unit 29 and an integrator 25. The difference 21 between the output of a command setting unit 19 and a detected value of controlled variable, a command 23 after the lapse of a lead time and a predicted disturbance 24 after the lapse of the lead time are applied to the predictor 22, the output of which is transmitted to the integrator 25 by pulses generated by a pulse generator 28. Then, the integrator produces a command signal for the control system 10
