摘要
为解决量化量测下传感器量化水平的选取问题,对于给定的系统滤波方差约束指标,设计了一种容许量化水平尽可能低的滤波器。给出了一种估计误差协方差系统稳定性的条件和当前估计型稳态滤波的线性矩阵不等式(LMI)计算方法。工程意义在于满足系统估计误差方差精度的前提下,尽可能低的量化水平代表着设计人员可以选择分辨率更低的传感器。通过仿真算例说明了算法的有效性。
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.
