Elastic coupled multi-machine system (ECMMS) is a one of the MIMO nonlinear complicated systems in industry. In such system, mechanical vibrations are resulted due to mechanical elastic coupling through shafts of the multiple motors of the system. One solution is to apply local controller for each motor of the system. The local controllers have to be adaptive to maintain the alignment irrespective of multiple or shared load variations and other variable disturbances. So, this paper presents a method to equalize against the resulted mechanical oscillation, and to maintain the alignment among motors in the ECMMS by designing a decentralized control system associated with an adaptation method of the parameters of local controllers to be automatically adapted with variable operating conditions. An experimental set-up of ECMMS is used to apply the proposed approach practically. The simulation data are compared to the real time data provided from the experimental set-up.
