Abstract :
This paper proposes a simulator-based foresight control approach for nonlinear plant based on system identification. In the proposed method, as a main part of the simulator-based foresight control system, a simulator of an exact plant model of non-affine nonlinear plant is first constructed. If relative degree of disturbance is smaller than control input, servo type filter will be then installed in series of disturbance line in order to adjust relative degree. Next, a control target equation which defines pole assignment for stable output error convergence is determined. Based on this control target equation, the control input for non-affine type nonlinear plant is generated. In this paper, the control of a boiler was implemented by use of the proposed method. The simulation results verified the effectiveness of the proposed method.
