为了解决船舶电力推进中转子磁场定向矢量控制定子电压方程中耦合项的影响,获得更好的动态性能和鲁棒性,本文提出了一种改进型自抗扰控制器,对自抗控制器典型结构做了一定的简化,并将其应用于船舶电力推进中的异步电机转子磁场定向矢量控制,实现了船舶电力推进中的异步电机磁链和转矩的快速调节。仿真结果表明,该控制系统具有优异的动态控制性能,而且参数鲁棒性较强。

In order propulsion, to get to reduce the impact of cross-coupling of vector control in ship electric dynamic and robustness, an improved active disturbance rejection controller（ADRC） was designed and implemented for robust control of induction motors. The improved algorithm applied in ship electric propulsion results in faster response with a simplified object. Simulation results show the control system has good dynamic performance and gives robust control with parameter variations.
