Dynamic Recurrent Neural Networks for Identification of a Multivariable Nonlinear Evaporation System F. Garces, C.Kambhampati and K. Warwick Abstract ******** This paper proposes an indentification technique for a nonlinear evaporator system. Extending an early result to multi-input multi- output (MIMO) systems [6], the technique approaches a nonlinear multivariable identification based on a dynamic recurrent neural network (DRNN). The method results on a state space nonlinear model of the evaporator system identified. The network and weight- updating algorithm proposed make the method remarkably easy to implement.
