将全阶状态观测器技术应用于船舶推进感应电机无速度传感器控制系统中，实现对推进电机转速的实时辨识。以定子电流和转子磁链为状态变量，构建全阶状态观测器。再以全阶状态观测器为可调模型，驱动电机为参考模型，使用模型参考自适应的方法对电机转速进行辨识。针对转速估算系统低速区域不稳定问题，设计出能保证系统在低速时保持稳定的反馈增益矩阵设计准则。在Matlab/Simulink仿真环境下进行仿真。
In order to achieve the real-time speed of Ship drive Induction motor,speed sensorless technology based on the full order state observers is applied to the induction motor control system. Build the full-order state observer with stator current and rotor flux as state variables, then set the full order state observer as the adjustable model, drive motor as reference model, use the model reference adaptive method to identify the motor speed in time. In view of the instability of the speed estimation system at low speed regional, try to set design criteria for feedback gain matrix that can guarantee the system stability in low speed regional. The simulation is carried out under the Matlab/Simulink simulation environment. Experimental results show that the design of the feedback gain matrix can identify the motor speed very well in the low speed regional.
