Application of Adaptive Data Fusion and Fuzzy Control in Correcting Geometric Parameters of Pantograph Catenaries

Good pantograph catenary relationship the guarantee of a safe power supply catenary system, the parameter accuracy, and the error correction degree of its geometric parameters (pull-out value and guiding height) are the premise to measuring the safety of pantograph catenary system. The model is changeable in dynamic geometric parameter detection, complex structure, and high distortion. First, a data fusion error control method is adopted, and the adaptive fuzzy control theory of pantograph catenary system operation is combined, from model building, data sampling, and adaptive control strategy. Second, the distortion model of pantograph catenary system geometric parameters in operation is corrected, and fuzzy control theory is used to find the minimum mean square error of geometric parameters from constraint sets. Verified by MATLAB simulation, the control strategy can effectively detect and correct the dynamic geometric parameters of the pantograph catenary system in real-time, ensuring normal and safe operation of train operation.
