Abstract：

For the nonlinear problem on clamp rotation system of forging manipulator by the hydraulic servo driving, a modeling method of the clamp rotation system was proposed based on T-S fuzzy modeling. According to the nonlinear characteristics of the clamp rotation system, the state space of the clamp rotation system in the forging manipulator was divided into several sub spaces to build a T-S fuzzy model with the uncertain parameters. Then, the fuzzy rules and membership function parameters in fuzzy inference system were adjusted by adaptive neuro-fuzzy inference(ANFIS), and the fuzzy rules and membership function were produced. Finally, the rationality of the T-S fuzzy model was validated by the experiment. The experimental results show that the calculated values by T-S fuzzy model of the clamp rotation system are basically consistent with the measuring values by the actual system, and the established T-S fuzzy model of the clamp rotation system provides the foundation for the control of the clamp rotation system.
