This method is based on drawing the frequency characteristic of decoupler and its estimation by using of a proper, stable and causal transfer function in a determined frequency range.Then has been discussed about the relationship between design decoupler and controller and its role in reducing the interactions of loops. Finally the sequential loop closing method with relay test and PID controllers is combined with the proposed decoupler design method. Successful results of this method in decoupling the multivariable system is shown with simulation. }, URL = {http://joc.kntu.ac.ir/article-1-79-en.html}, eprint = {http://joc.kntu.ac.ir/article-1-79-en.pdf}, journal = {Journal of Control}, doi = {}, year = {2011} }
