矢量控制与直接转矩控制是当前主要的两种电机变频调速控制方法,已在两相交流感应电机中得到
了应用。分析了两相不对称电机矢量控制和直接转矩控制原理以及两相三桥臂逆变器的SVPWM实现方法;
运用Matlab的Simulink建立了两相不对称交流感应电机矢量控制和直接转矩控制调速系统的仿真模型,并
对两种控制系统进行了仿真研究,给出了仿真波形,进行了特性比较.
关键词:两相电机;矢量控制;直接转矩控制;SVPWM;MATLAB;仿真(Vector Control and Direct Torque Control is currently the main method of frequency control of two motors, has been in two-phase AC induction motor has been applied. Analysis of asymmetric two-phase motor vector control and direct torque control principle and two-phase SVPWM inverter arm Bridge Implementation the use of Matlab in Simulink to establish a two-phase AC induction motor asymmetry of vector control and direct torque control modulation speed of system simulation models, and the two control system was simulated, the simulation waveform characteristics were compared. Key words: two-phase motor vector control direct torque control SVPWM MATLAB Simulation)

说明: 3) 跨平台文档结构的调整 项目文档是始终贯穿着整个系统的,但由于Windows系统与其他系统如Linux等的文档结构不同,项目的可移植性将会受到限制,因此强调可移植性的本系统中跨平台文档结构的调整是必不可少的,我们预计在这一阶段以Windows 和 Linux为基础出2套相应的代码版本,基础代码部分不变,只是在文档接口及对应的应用工具上做出相应的选择。预计所需时间为二个月,包括平台的移植,接口的研究和开发等(3) cross-platform document the restructuring of the project document is always run through the whole system, but the Windows system and other systems such as Linux and other documents of different structures, the project will be subject to the portability restrictions of the emphasis on portability cross-platform file system structure is essential, we expect at this stage in Windows and Linux based on the 2 versions of the corresponding code, the basis of some of the same code, but in the document application interface and the corresponding tools choices accordingly. Expected time required for months, including platform migration, interfaces, such as research and development)
