| Abstract: | A dynamics model based on the non-symmetry cylinder controlled by the symmetry value is established in this paper. This method can be adapted to the math modeling of electro-hydraulic position servo control system. Fuzzy control theory is used in servo control system, and a fuzzy PID controller of three dimensions has been designed. The result of visual simulation in Matlab/Stimulink shows that the dynamic and static property greatly improves, and the response speed of the system greatly quickens. A feasible thinking and method for the research fuzzy controller of multitude-input and multitude-output(MIMO) is provided. |
