Title:
ADAPTIVE CONTROL DEVICE
Document Type and Number:
Japanese Patent JPS6280705
Kind Code:
A
Abstract:
PURPOSE:To obtain an estimation mechanism prevented from adverse influence due to transient disturbance to be applied to a plant by utilizing a disturbance suppressing effect based upon a closed loop system. CONSTITUTION:Instead of the estimation of dynamic characteristics of an controlled system, the dynamic characteristics of a manipulated variable operating part, i.e. the whole closed loop including a controller, is estimated. Since the whole controlled loop including the PI controller is identified, the DC component of disturbance d(t) disappears completely from a plant output y(t) and the influence of a low frequency component of the disturbance is also comparatively reduced, the low frequency characteristics of the controlled system can be accurately estimated. Since the whole closed loop system is modeled, the PI controller is permitted to be a continuous system or a discrete system with an extremely thin control period.
