摘 要
异步电机因其结构简单、运行可靠和成本低廉等优势，在工业领域中得到了广泛应用，但传统控制方法难以满足高性能驱动系统对动态响应和稳态精度的要求。为解决这一问题，本文基于矢量控制技术展开深入研究，旨在提高异步电机驱动系统的性能表现。研究首先分析了异步电机的数学模型，并通过坐标变换实现解耦控制，从而将复杂的多变量系统转化为易于控制的直流电机模型。在此基础上，设计了一种改进型转子磁链观测器，有效解决了传统方法在低速或静止状态下观测精度不足的问题。同时，引入自适应调节机制优化控制器参数，显著提升了系统的鲁棒性和抗干扰能力。

Abstract
Asynchronous motor is widely used in the industrial field due to its advantages of simple structure, reliable operation and low cost, but the traditional control method is difficult to meet the requirements of high-performance drive system for dynamic response and steady-state accuracy. In order to solve this problem, this paper focuses on the vector control technology to improve the performance of the synchronous motor drive system. The study first analyzes the mathematical model of Asynchronous motor and realizes decoupling control through coordinate transformation, thus transforming the complex multivariable system into an easily controllable DC motor model. Furthermore, a modified rotor magnetic chain observer is designed to solve the problem of insufficient observation accuracy at low speed or stationary state. At the same time, the introduction of adaptive regulation mechanism to optimize the controller parameters, which significantly improves the robustness and anti-interference ability of the system.
