Based on the principle of frequency control of motor speed,and motor unified theory,the dynamic mathematical model of three phase asynchronous motor is established under three-phase coordinate transformation.To analyse this dynamic mathematical model,a simulation model is established under Matlab/Simulink and simulation studies are performed to verify the feasibility of the proposed vector controlled drive.The results not only indicate the validity of the dynamic mathematical model and simulation model,but also show that by adjusting simulation parameters in each model,perfect simulation waveform is obtained.

Blended learning has become an important practice in colleges and universities all over China.Taking the case of aerobics reform in Hunan University of Finance and Economics,we have investigated the instructional design of aerobics on blended learning.In order to improve teaching efficiency and the ability of the students' lifelong sports,aerobics teaching on blended learning is divided into such five stages as pre-analysis and design,online learning,face-to-face discussion and evaluation.The specific tasks and the teachers' role in all stages are also analyzed.
