摘要：
Relative to gear shaping and gear hob, using gear slotting produces herringbone gear which is used in nuclear power turbine speed redactor has more obvious technical and economic benefits, but profile angle error of slotting cutter causes profile error and base pitch deviation of herringbone gear. It will result in high-frequency noise which damages the tactical and technical performance of warship. By analyzed the wire cutting system of rack cutter used in MAAG type gear machining for herringbone gear, the mathematical model of error prediction for rack cutter profile angle was founded. On the base of model of error prediction, the principle of error control and the method of revision control are presented. Finally, the example of prediction and control is provided.

摘要：
The chaotic phenomena of a permanent magnet synchronous motor (PMSM) under certain circumstances were studied based on the error analysis of the stator flux observer output by parameter change of the permanent magnet synchronous motor, PMSM model with chaotic features was built, and the chaotic curves were gained based on PMSM mathematic model. A dual fuzzy controller was designed for the direct torque control (DTC) system of the PMSM. The simulation results prove that control effect on the chaotic phenomenon of the PMSM-DTC system by the dual fuzzy control is good, and the dynamic and static performances of the PMSM-DTC system will be improved. Also the ripple of torque and flux can be reduced and the response speed can be improved.
