基于DSP的异步电动机直接转矩控制系统设计与研究

摘要

The theory of direct torque control applied in induction motor variable frequency control system is analyzed, and then MATLAB simulation software has been used to establish a DSP-based direct torque control inverter system simulation model, the corresponding simulation result curve; designed a TMS320LF2406 DSP core. The frequency control hardware system test results show that the system has an excellent dynamic and static performance.%分析了直接转矩控制在异步电动机变频控制系统中的应用,然后利用MATLAB仿真软件建立了基于DSP的直接转矩控制变频系统仿真模型,得到相应的仿真结果曲线.设计了以TMS320LF2406 DSP为核心的变频调速硬件系统,实验结果表明该系统具有良好的动、静态特性.
