| Abstract: | Utilizing the nonlinear mapping capability of BP neural networks, the pertaining object of control in the coordinated control system is being identified, and consequently its dynamic model established, on the basis of which optimization of the parameters of the controller in the coordinated control system is being studied and a coordinated control strategy based on predictive control with neural network proposed. In this way problems of profound coupling and nonlinearity, existing in coordinated control systems, can quite well be solved. Simulation tests indicate that such a system is featured by higher tracking speed, improved precision of adjustment and strengthened resistance capability against disturbances. Figs 6 and refs 7. |
