內藏式永磁同步電機之滑模速度控制及自適應滑模電流控制研究

Abstract

本文主旨為研究滑模控制應用於內藏式永磁同步電機驅動系統中之速度控制及電流控制，並於定轉矩區結合每安培最大轉矩的控制策略。滑模控制相較於比例積分控制具有較快的響應速度和更具強健性的優點，使其在高性能電機驅動系統應用中具有重要價值。為了使滑模控制的強健性更加提升，在轉速控制中本論文使用了滑模觀測器以觀測系統的轉矩負載及干擾值，電流控制中使用自適應滑模控制並設計了變係數的自適應增益，確保了在參數不匹配的情境，能消除抖震且仍具滑模可達性。最後，通過模擬軟體MATLAB/Simulink驗證所提出方法的有效性及其在提升電機驅動系統整體性能方面的潛力。

The main objective of this thesis is to study the application of Sliding Mode Control (SMC) in the speed and current control of Interior Permanent Magnet Synchronous Motor (IPMSM) drive systems, combined with the Maximum Torque Per Ampere (MTPA) control strategy in the constant torque region. Compared with Proportional-Integral (PI) control, sliding mode control offers advantages such as faster response and greater robustness, making it valuable in high-performance motor drive system applications. To further enhance the robustness of sliding mode control, this paper employs a Sliding Mode Observer (SMO) in speed control to observe the system's torque load and disturbance values. In current control, an adaptive sliding mode control with a variable adaptive gain was designed to ensure that in the presence of parameter mismatches, chattering is eliminated while maintaining sliding mode reachability. Finally, the effectiveness of the proposed method and its potential to improve the overall performance of the motor drive system are verified through MATLAB/Simulink software simulations.
