a modern feedback approach

... ways The relay feedback approach, for its simplicity and light-computational load, is a good candidate However, due to dissimilarity of linear and nonlinear systems, there are still great challenges ... linear-nonlinear hybrid systems are mainly categorized into time domain based and frequency domain based approaches For the time domain approach, current existing methods based on relay -feedback ... the advantages of relay feedback are totally lost Furthermore, the reliability of such approach is also a doubt, since the estimation of parameters using multi-parameter nonlinear optimization...
