Nonlinear Networked Control Systems with Random Nature using Neural Approach and Dynamic Bayesian Networks

Nonlinear Networked Control Systems with Random Nature using Neural Approach and Dynamic Bayesian Networks

We propose an intelligent predictive control approach for a nonlinear networked control system (NCS) with time-varying delay and random observation. The control is given by the sum of a nominal control and a corrective control. The nominal control is determined analytically using a linearized system model with fixed time delay. The corrective control is generated online by a neural network optimizer. A Markov chain (MC) dynamic Bayesian network (DBN) predicts the dynamics of the stochastic system online to allow predictive control design. We apply our proposed method to a satellite attitude control system and evaluate its control performance through computer simulation.
