Study of H_∞ control for propulsion motor of deep submergence vehicle

为了抑制转子电阻参数摄动和洋流、海浪引起的转矩波动对深潜艇推进电机调速系统的影响,对应用状态反馈鲁棒控制方法来处理推进感应电动机磁场定向下的矢量控制问题进行了研究,并在此基础上,根据建立的深潜艇直航运动模型和螺旋桨四象限动态工作情况下的仿真模型,进行了深潜艇直航推进仿真.仿真结果表明,这种方法能够有效抑制转子参数摄动和负载转矩波动对系统动态性能的影响.

In order to attenuating the effect of rotor resistance variety and torque disturbance caused by ocean current and surf on the speed-regulation system of the electric propulsion motor in a deep submergence vehicle （DSV）, a method is studied that employs state feedback robust control to deal with the vector control of propulsive induction motor problem under the magnetic field oriented condition. Movement simulation along X-shift of DSV is made based on the simulation models of DSV movement models and four-quadrant dynamic working situation of the propeller. The simulation results show that the method can attenuate the influence of rotor parameter perturbation and load torque disturbance on the dynamic performance of the system.
