Abstract
In our recent publication Pramana – J Phys 79 81 2012 DOI 101007/s1204301202856 our statement on adaptive antisynchronization AS controller design is incorrect In this erratum we propose a correct control law The corresponding proof is also given to demonstrate the effectiveness of the proposed control strategyIn our recent publication Pramana – J Phys 79 81 2012 our statement on adaptive antisynchronization AS controller eq 10 is incorrect because the control input had the unknown parameter vectors boldsymbolupalpha and boldsymbolupbeta as also the disturbances textbfdprime and textbfdprimeprime were used The vectors boldsymbolupalpha and boldsymbolupbeta in eq 10 should be replaced by hat boldsymbolupalpha and hat boldsymbolupbeta Furthermore we were wrong to use external disturbances in control input The fact is that disturbances are unknown and very trivial and it is difficult to know disturbances exactly Therefore the proposed control input in the previous work is not applicable and realistic In this erratum we propose a new control law which contains a compensator that is introduced to eliminate the influence of the external uncertainties The corresponding proof is also given
