For this purpose, synchronization schemes based on interconnections between the systems, feedback controllers and observers are proposed. Because mechanical systems include a large variety of systems, and since it is impossible to address all of them, the book focuses on robot manipulators. Nonetheless the ideas developed here can be 410 0$aWorld Scientific series on nonlinear science.$nSeries A,$pMonographs and treatises ;$vv. 46. 606 $aRobots$xControl systems 606 $aSynchronization 608 $aElectronic books. 615 0$aRobots$xControl systems. 615 0$aSynchronization. 676 $a621.3133 700 $aNijmeijer$b H$g(Hendrik),$f1955-$027871 701 $aRodriguez-Angeles$b Alejandro$0989866 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910454317303321 996 $aSynchronization of mechanical systems$92264105 997 $aUNINA
