Application of Flexible Fuzzy Control in Membrane Structure Inflation System

In order to eliminate steady-state errors and chatter caused by quantization error of the conventional fuzzy controller, based on the self-adjustment of quantified proportionality factors fuzzy controller, this paper establishes the flexible fuzzy controller, and can achieve the online parameters self-adjusting function. This method is used in inflation process of pneumatic membrane structure, which enables the inflation process to produce the smooth change in flexible frequency conversion. The results show that the flexible fuzzy logic controller has fast response speed and small steady-state error, meanwhile the parameters change of the controlled object has some flexible adaptability.
