【Abstract】 To improve the control precision of the traditional fuzzy controllers, a high precision fuzzy control scheme was studied and modified. A novel scheme was developed with only one control searching table to recursively self adjust quantization factor and scale factor over a small error area to reduce steady state error. A simulation test shows that this new scheme not only retains the merits of the former scheme which had high precision but also overcomes its shortcoming which hindered the fast response and the nonlinear control of the PD fuzzy controller. In addition, it significantly reduces the calculational time and guarantees the real time control.更多还原
