摘要
提出了一种估算永磁同步电机转子角速度的降维线性Luenberger算法,该算法利用永磁同步电机定子交轴电流和转速方程构造观测器,实时估算电机的转子角速度。此观测器简单易行,通过特征值的配置可以获得快速的收敛速度;同时,采用反推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。Matlab的仿真及实验表明系统设计的有效性和可行性。
A control of permanent magnet synchronous motor by the estimated rotor speed using a new reduced-order Luenberger observer is proposed.The motor speed is acquired through observer constructed with stator q-axis current and speed equations.The observer is simple and can achieve fast convergence through eigenvalues placement.Backstepping control is used to design system controllers and the system can achieve fast speed tracking and torqure response.Matlab simulation and experimental result is applied to proves the efficiency and feasibility of system design.
