摘要
介绍了直接转矩控制系统和控制原理,并对系统建立状态空间数学模型。采用了磁链和转矩的优化设计思想。借助于M atlab给出了DTC的仿真波形。仿真和实验表明:DTC控制具有更好的稳定性、较强的鲁棒性和抑制扰动的能力。
Direct torque control system and control theory were introduced and state space mathematics model for system was established. Adopting flux and torque control systematic optimization design thought, DTC control simulation waveform was given with the help of Matlab. Simulate and experiment shows that DTC theoretical control has better stability, comparatively strong robust and the ability of restraining disturbance.
