| 摘要: |
| 利用本质上是非线性反馈的无源性控制（PBC）策略，实现同步电机的全局稳定和转矩、转速跟踪控制。建立了同步电机的Euler-Lagrange模型；在此基础上利用无源性滑模控制方法构建转矩、转速动态跟踪控制器，在非线性负载时变未知情形下，实现了转子磁链、转速的期望轨迹渐近跟踪；针对实际运行时同步电机参数具有不确定性的问题，将无源性滑模控制方法与自适应策略相结合，实现电阻参数的自调整，有效抑制负载变化时产生的转矩跟踪误差。基于dSPACE的实验结果证明了该方法具有形式简单、无奇异点、鲁棒性好的特点。 |

| Abstract: |
| A PBC（Passivity-Based Control） method is developed to realize the global stability of three-phase synchronous motors and the tracking of its torque and speed. Its Euler-Lagrange model is determined and its dynamic tracking controller is proposed with the passivity-based sliding mode control scheme，which realizes the asymptotic tracking of rotor flux and speed trajectories with time-varying nonlinear load. Combined with the adaptive control strategy，the developed PBC system adaptively adjusts the resistance parameter to repress the torque tracking error. Its simple structure，lack of singularity and good robustness are testified by the experiments based on dSPACE. |
