To solve the problem of difficult construction of appropriate fuzzy rules in the generalized type-2 fuzzy system due to a lack of expertise in complex situations, a method for generating generalized type-2 fuzzy sets and fuzzy rules based on the activation intensity of input data was proposed. The fuzzy rules of generalized type-2 fuzzy systems were constructed by a data-driven self-organization strategy, and the parameters of the front and rear parts of the system were optimized by the iterative least squares and gradient descent methods. Finally, the tracking simulation of the nonlinear system was conducted in the conditions of no disturbance and noise disturbance . The experimental results revealed that the generalized type-2 fuzzy system generated by the self-organizing rules is effective, and the reference trajectory can be tracked with high accuracy.
