ABSTRACT:
A control system for a plant includes a sensor for detecting an output from the plant, an adaptive controller for controlling a manipulated variable applied to control of the plant in a manner such that an output from the sensor becomes equal to a desired value, and an adaptive parameter vector-adjusting mechanism for adjusting an adaptive parameter vector used by the adaptive controller. The adaptive parameter vector-adjusting mechanism is constructed such that an updating component for updating the adaptive parameter vector is added to an initial value of the adaptive parameter vector, and updates the adaptive parameter vector by multiplying at least part of preceding values of the updating component by a predetermined coefficient which is larger than 0 but smaller than 1.
