摘要
文章基于异步电机直接转矩控制原理,选用DSP的TMS320F281 2作为主控芯片,设计了直接转矩控制调速系统,介绍了系统的硬件构成及软件实现,并建立了仿真模型,采用Matlab/Simuli nk软件进行了仿真实验。结果证明,该调速系统启动时间短、转矩脉动较小、稳态时转速平稳,能够获得转矩的高品质动态性能。
This paper analyzed principle of direct torque control（DTC）for asynchronousmachine, chose the TMS320F2812 as the main chip of control circuit to design the DTCspeed-regulation system, introduced hardware structure and software realization, built upthe simulation model of the system and performed an experiment to the system with Matlab/Simulink. The results confirmed that the system had a short start time, smarl torque ripple,stable steady-state speed, achieved the high-quality torque dynamic nature.
