A design method of generalized root-loci for MIMO systems
Xiao‐Ming Xu, Zhiming Wu, Zhongjun Zhang · 1986
The classical root-loci techniques have been found to be unable to analyse and design MIMO systems. The multivariable root-loci methods developed in recent years, as only one parameter of the system can be adjusted at a time, are still difficult to meet the requirements of most practical systems. This paper first gives a definition of the generalized root-loci, from which all kinds of multivariable root-loci can be unified in such a framework. The authors then propose a design method of the generalized root-loci with multi-parameters. By this method, the advantages of classical root-loci method are preserved and yet the practical experiences of engineers are taken into account. Therefore the method is both convenient and efficient for designing MIMO systems. An explanatory example is included.
