This paper presents a pole-placement based control algorithm to treat ISA Fieldbus H1 delay problems. A digital network delay model is embedded with the process model in order to design a suitable closed-loop controller. The effect of different values of network delay against sampling time is analyzed. Pole-placement technique should not simplify zeros in(More)
This paper derived a new formulation for Lyapunov stability analysis of Neural Generalized Predictive Controller (NGPC). Paper also applied simple technique to improve NGPC stability by using internal model of disturbance in feed forward. Finally, paper presents comparison study for the effect of using internal model principle with severe nonlinear process(More)
This paper emphasizes on the stability analysis of the Neural Generalized Predictive Controller (NGPC) algorithm using Lyapunov methods. NGPC is a hybrid combination between the well known GPC algorithm and a Feed Forward Multi Layer Perceptron (FF MLP) neural network model identifier. This combination leads to a better stability characteristics in the(More)
