In this paper, a continuous time recurrent neural network (CTRNN) is developed
to be used in nonlinear model predictive control (NMPC) context. The neural
network represented in a general nonlinear state-space form is used to predict
the future dynamic behavior of the nonlinear process in real time. An efficient
training algorithm for the proposed network is developed using automatic
differentiation (AD) techniques. By automatically generating Taylor
coefficients, the algorithm not only solves the differentiation equations of the
network but also produces the sensitivity for the training problem. The same
approach is also used to solve the online optimization problem in the predictive
controller. The proposed neural network and the nonlinear predictive controller
were tested on an evaporation case study. A good model fitting for the nonlinear
plant is obtained using the new method. A comparison with other approaches shows
that the new algorithm can considerably reduce network training time and improve
solution accuracy. The CTRNN trained is used as an internal model in a
predictive controller and results in good performance under different operating
conditions. |
