Kalman Filtering for Delayed Singular Systems with Multiplicative Noise被引量：2: 2016年; Kalman filtering problem for singular systems is dealt with, where the measurements consist of instantaneous measurements and delayed ones, and the plant includes multiplicative noise. By utilizing standard singular value decomposition, the restricted equivalent delayed system is presented, and the Kalman filters for the restricted equivalent system are given by using the well-known re-organization of innovation analysis lemma. The optimal Kalman filter for the original system is given based on the above Kalman filter by recursive Riccati equations, and a numerical example is presented to show the validity and efficiency of the proposed approach, where the comparison between the filter and predictor is also given. © 2014 Chinese Association of Automation.; Xiao LuLinglong WangHaixia WangXianghua Wang; 关键词：ESTIMATION FILTRATION

基于Tustin变换的分数阶微分算子近似离散化被引量：7: 2015年; 分数阶微分算子的离散化是分数阶控制器数字化实现的关键。对基于Tustin变换的分数阶微分算子直接离散化方法进行了研究和比较。概述了分数阶微积分及其离散化,介绍了用于Tustin算子展开的幂级数展开法、连分式展开法和Muir递归展开法;并给出了展开方法的算法表达式。定义了误差指标函数,举例比较了以上三种分数阶微分算子离散化方法的优缺点。仿真比较表明:连分式展开法在较宽频带内对分数阶微分算子具有最好的近似特性,但计算复杂度大;幂级数展开法和Muir递归展开法近似效果相当,但前者具有较大计算效率优势。在分数阶数字控制器实现过程中应根据具体情况选择合适的分数阶算子离散化方法。; 宋保业许琳卢晓; 关键词：分数阶微积分
