Abstract: Based on the review of traditional control theories and some intelligent control theories,their limitations are discussed,then the human-imitating intelligent control method is presented which is based on the physical model.The mechanism of this method is explained and the procedure of designing the human-imitating control law is introduced through its successful application to stabilizing the two-degree-of-freedom single inverted pendulum.As for the complicated nonlinear objects,applying this human-imitating intelligent control method can achieve satisfactory results as long as the object's physical model is available.

Key words: intelligent control, reduction, fuzzy control, artificial neural network
