MODEL NORM TYPE ADAPTIVE CONTROLLER
Document Type and Number:
Japanese Patent JPH0363704
Kind Code:
A
Abstract:
PURPOSE:To settle a problem of the model follow-up deterioration when there is a zero point by a simple constitution, and also, to adjust the model follow-up gain by providing a filter having the same pole as a zero point of a plant. CONSTITUTION:A filter 2 having a pole of a value being equal to a zero point of a plant 1 is inserted into this side of an input of the plant 1, and the zero point of the plant 1 is offset. Also, a means 7 for managing a follow-up state to a model 4 is provided, and the gain of an adaptive system is adjusted. In such a way, when the filter 2 having a pole of the same value as the zero point is inserted into the input of the plant 1, the zero point of the plant 1 is offset, and it becomes equivalent to the plant having no zero point. Also, when the model follow-up performance is insufficient, the gain is raised by the managing means 7, and as a result of raising the gain, when the model follow-up performance is deteriorated, the adjustment to correct gain is executed by lowering the gain by the managing means 7.
