The Application Of A New Control Algorithm In Main Stream Temperature Control System

In this paper, a new intelligent feedforward and feedback control algorithm is given for main stream temperature control system with the properties of high inertia and strong delay and time-variation and multi-disturbances. In feedback, a nonlinear PID controller is designed for the control system based on nonlinear Tracking Differentiator (TD) and variable arguments PID modification, and a modified genetic algorithm is given for parameters optimization of the controller. In feedforward, based on the neural network control theory, a feedforward controller is designed for disturbances overcoming of the control system. The simulation manifests that the new control algorithm has good control quality and good robustness and good anti-disturbances ability.Liu Jian-dong(Control Theory and Control Engineering) Directed by Prof. Zhang Luan-ying...
