Abstract:
A plant control system for controlling a plant, comprising:an actuator for generating an input to the plant;first detecting means for detecting an output from the plant;manipulated variable determining means for sequentially determining a manipulated variable which determines the input to the plant to equalize the output from said first detecting means to a predetermined target value;actuator control means for controlling operation of said actuator based on the manipulated variable determined by said manipulated variable determining means; andestimating means for sequentially generating data representing an estimated value of the output from said first detecting means after a total dead time which is the sum of a first dead time of said plant and a second dead time of a system which comprises said actuator and said actuator control means;said manipulated variable determining means comprising means for determining said manipulated variable based on the data generated by said estimating means.
