ADAPTIVE FEEDBACK PASSIVITY OF A CLASS OF NONLINEAR SYSTEMS

Passivity is the property stating that any storage energy in a system is not larger than the energy supplied to it from external sources. This paper considers adaptive feedback passivation for a class of nonlinear systems. A nonlinear system with unknown constant parameters is transformed via feedback into a new system. An appropriate update law is designed so that the new transformed system is passive. In fact the system is passive via feedback if the unknown parameters are replaced with their suitable estimates.
