摘要 研究一类多速率数据采样系统基于等价空间的快速残差产生问题.首先应用一种提升技术,建立多速率数据采样系统的线性时不变提升模型,并以提升模型为基础将基于等价空间的残差产生器设计问题归结为最小化问题.然后,利用该最小化问题解不唯一的特点,求得满足因果关系的最优残差产生器.进一步,应用逆提升技术实现残差产生同步于测量输出采样的快速化.算例验证了所提方法的有效性. Fast residual-generation based on the parity-space is studied for a class of multi-rate sampled-data systems. By applying a lifting technique, we develop a linear time-invariant system to model the multi-rate sampled-data systems and, based on this model, treat the design of the parity-space-based residual generator as a minimization problem. A causal residual generator is obtained by making use of the ununiqueness of the optimal solutions to the minimization problem. Furthermore, a fast synchronization of the residual signal with the measurement output can be realized by employing an inverse lifting technique. A numerical example is given to show the effectiveness of the proposed method.
