Abstract:

In order to compensate the time delay, the plant and network are regarded as one time varying system, which is predicted by least square estimation. Based on this, a Smith compensator is used to compensate the time delay of the system. The complex controller including a cerebellar model articulation controller of neural networks and a PD controller is applied to the system to weaken the prediction error further, while the control performance can be improved. The simulation results show the method can improve the control performance.
