摘要
设计了一种基于全阶观测器的自适应磁链观测器,通过引入定子电流反馈使观测器对电机参数具有一定的鲁棒性,减少了电机参数的误差以及参数在运行过程中的变化对磁链观测准确性的影响。同时在系统中实现了电机转速的在线辨识,并对不同的离散化方法进行了比较,在基于TMS320F2407型DSP的异步电机控制系统上完成了控制系统的设计和实验,实验结果验证了自适应磁链观测器的有效性。
A novel adaptive flux observer based on full-order observer is designed, in which motor current feedback is used to improve the robustness for the observer to the motor parameters. It reduces the errors of motor parameters and the influence on observation results caused by the inaccuracy and variety of the parameters. The online identifications of the motor speed and discretization o f full-order observer are also introduced in this paper. A motor control system with TMS320F2407 as the controller is designed. Experiments results verify the effect of the proposed method.
