摘要
本文利用永磁同步电动机定子交轴电流和转速方程构造降维线性Luenberger观测器来获得电动机的转速,观测器简单易行,通过特征值的配置可以获得快速的收敛速度。本文采用直接反馈线性控制策略来设计系统控制器,使系统具有良好的速度跟踪和转矩响应。通过Matlab的仿真,验证了系统设计的有效性和可行性。
The speed of permanent magnet synchronous motor was acquired using reduced-order I.uenberger observer constructed from stator q-axis current and speed equation. The observer is simple and achieves fast convergence with the eigenvalues setting. The system controller was designed using direct feedback linearization control. The system features fast speed tracking and torque response. Matlab simulation result proves the efficiency and feasibility of the system design.
