ESTIMATION METHOD OF POSITION USING OBSERVER

摘要

PROBLEM TO BE SOLVED: To reduce the delay of an observer calculation position based on quantization processing more than ever.SOLUTION: An observer includes a state variable correction amount based on the position difference between the position measurement value of an object obtained through quantization processing from a measurement apparatus and the position measurement value of the object determined from the observer. When the position difference is within a quantification unit of the measurement apparatus, the state variable correction amount is set within a previously determined target estimation accuracy unit (for example, 0).SELECTED DRAWING: Figure 6
