Abstract
An improved function-type contraction-expansion factor is designed in this paper. Optimization criterion rules of contraction-expansion factor are designed by analyzing the changing relationship between the input signals of fuzzy controller and contraction-expansion factor. And then, an improved contraction-expansion factor is designed to optimize the structure and improve the control quality of the system. Based on Lyapunov stability theory, the stability of variable universe fuzzy control system with designed contraction-expansion factor is proved. Simulation results show that the design of variable universe fuzzy control method can effectively improve system performance.
