TLDR
The simulating results prove that the improved fuzzy controller can really eliminate stable state error and improve the controlling precision of fuzzy controller.Abstract:
To counter the problem of lower controlling precision of fuzzy controller, this paper puts forward a method to improve controlling precision of fuzzy controller. First, the paper analyses the reason of lower controlling precision of conventional fuzzy controller, then puts forward a method to solve this problem and gives its design method, finally gives the simulating results of the improved fuzzy controller and compares with conventional fuzzy controller. The simulating results prove that the improved fuzzy controller can really eliminate stable state error and improve the controlling precision of fuzzy controller. The improved fuzzy controller retains the nonlinear controlling property of conventional fuzzy controller, its design is simple and its realization is easy, it has certain practical application value.read more
