%X In order to enhance the adaptability and stability of resistance spot welding(RSW), the variable universe RSW control method is put forward based on the variable universe control theory. First, the basic theory of variable universe fuzzy control theory is discussed. Second, the inputting membership functions, the outputting membership functions, the fuzzy control rules and the extension-contraction factors are designed; thus, a fuzzy controller based on normalized factors is developed. The extension-contraction factors are selected according to the fuzzy rulers in proposed controller. The detailed calculation steps of the algorithm are given. Finally, a practical prototype is tested with different control methods. The test results are analyzed and discussed; and the advantages of the proposed control algorithm are verified.
