Yuhao Zhang, Xiangru Xu

摘要:

线性约束切换系统是指切换序列受确定性有限自动机约束的线性切换系统。本文基于我们以前的结果,研究了如何生成一个渐近增长率接近约束切换系统的约束联合谱半径(CJSR)的矩阵序列,该结果揭示了约束切换系统和提升任意切换系统的等价性.利用平方和优化程序的对偶解,设计了一种算法,使提升后的任意切换系统产生一个矩阵序列,其渐近增长率接近于原约束切换系统的CJSR.它还表明,一种类型的现有算法设计的任意切换系统可以应用到提升系统,使所需的序列矩阵可以产生的约束切换系统。数值算例表明,与现有算法相比,所提算法具有更好的性能。

英文摘要:

Linear constrained switching systems are linear switched systems whose switching sequences are constrained by a deterministic finite automaton. This work investigates how to generate a sequence of matrices with an asymptotic growth rate close to the constrained joint spectral radius (CJSR) for constrained switching systems, based on our previous result that reveals the equivalence of a constrained switching system and a lifted arbitrary switching system. By using the dual solution of a sum-of-squares optimization program, an algorithm is designed for the lifted arbitrary switching system to produce a sequence of matrices with an asymptotic growth rate that is close to the CJSR of the original constrained switching system. It is also shown that a type of existing algorithms designed for arbitrary switching systems can be applied to the lifted system such that the desired sequence of matrices can be generated for the constrained switching system. Several numerical examples are provided to illustrate the better performance of the proposed algorithms compared with existing ones.
