doi:10.3969/j.issn.1000-1093.2012.06.020

Abstract

Abstract: In order to determine the quantization level of sensors in quantized measurements, a new filter with allowable quantization level as low as possible was designed for given constraints of variance. The condition of the stability of error covariance matrix and a LMI method for current-estimation-type steady filter were presented. It means that, on the premise of meeting the system estimation variance, the designers can choose the sensors with lower resolution. A numerical example shows the usefulness and flexibility of the proposed approach.

Key words: information processing, sensor, quantized measurement, filtering, resolution
