| 中文摘要 |
| 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.采用新颖的非线性控制策略———Backstepping———来设计速度跟踪和电流控制器,系统具有快速的速度跟踪和转矩响应.给出了系统的稳定性证明,并通过Matlab仿真,验证了系统设计的有效性和可行性. |
| 英文摘要 |
| The speed of a permanent magnet synchronous motor is acquired through a reduced-order Luenberger observer constructed through the stator q-axis current and speed equations.The observer is simple and can achieve fast convergence through adequate eigenvalues placement.A novel nonlinear control strategy —backstepping?— is used to design speed tracking and current control.The system can achieve fast speed tracking and torqure response.The proof of system stabilization is also given.Matlab simulation is performed to verify the efficiency and feasibility of the system design. |
