| 摘要: |
| 针对永磁同步电机(permanent magnet synchronous motor, PMSM)控制系统过度依赖精确模型的问题，提出一种基于动态线性化方式的无模型自适应快速终端滑模控制算法。首先，将电机运动方程转化为离散紧格式的动态线性化模型。基于新型快速幂次趋近律，结合紧格式型无模型自适应控制和离散快速终端滑模算法的优点，设计离散时间无模型自适应快速终端滑模控制律。其次，基于电机的输入和输出数据，根据准则函数构造伪偏导数(pseudo partial derivative, PPD)估计算法，实现了基于数据驱动的控制，并分析了PPD估计算法的收敛性与控制算法的稳定性。最后，仿真和实验结果表明，与传统控制策略和无模型自适应滑模控制对比，所提方法提高了PMSM驱动系统的响应速度和鲁棒性，且不再依赖精确系统模型。 |

| Abstract: |
| Aiming at the excessive reliance on accurate models in permanent magnet synchronous motor (PMSM) control, a model-free adaptive fast terminal sliding mode control algorithm based on dynamic linearization is proposed. First, the motor motion equations are transformed into a discrete compact-form dynamic linearization model. Combining a novel fast power reaching law with the advantages of compact-form model-free adaptive control and discrete fast terminal sliding mode algorithm, a discrete-time model-free adaptive fast terminal sliding mode control law is designed. Second, based on the motor input and output data, a pseudo partial derivative (PPD) estimation algorithm is constructed according to a performance criterion, realizing fully data-driven control. The convergence of the PPD estimation and the stability of the control algorithm are analyzed. Finally, compared with conventional control strategies and model-free adaptive sliding mode control, simulation and experimental results show that the proposed method improves the response speed and robustness of PMSM drive systems, while eliminating the need for an accurate system model. |
