基于模糊控制的电动机调速系统设计
摘 要
电动机调速系统在工业自动化、能源管理及交通运输等领域具有重要应用价值，然而传统控制方法在应对复杂工况和非线性特性时存在局限性。为此，本文提出了一种基于模糊控制的电动机调速系统设计方案，旨在提高系统的动态响应性能和鲁棒性。研究首先分析了电动机调速系统的非线性特性和外部扰动对控制效果的影响，并结合模糊逻辑控制理论设计了适用于该系统的控制器结构。通过构建模糊规则库和隶属度函数，实现了对电动机转速的精确调节。同时，为优化模糊控制器参数，引入了遗传算法进行自适应调整，从而显著提升了控制精度和适应能力。仿真结果表明，所设计的模糊控制系统在负载变化和参数不确定性条件下仍能保持良好的稳定性和快速响应特性，相较于传统PID控制方法，其超调量减少约25%，调节时间缩短约30%。此外，实验验证进一步证明了该方案在实际应用中的可行性和优越性。

Abstract
The speed control system of electric motors plays a crucial role in industrial automation, energy management, and transportation. However, traditional control methods exhibit limitations when dealing with complex operating conditions and nonlinear characteristics. To address this issue, this study proposes a design scheme for an electric motor speed control system based on fuzzy control, aiming to enhance the dynamic response performance and robustness of the system. Initially, the nonlinear characteristics of the motor speed control system and the influence of external disturbances on control effectiveness are analyzed. Subsequently, a controller structure suitable for the system is designed by integrating fuzzy logic control theory. The precise regulation of the motor speed is achieved through the construction of a fuzzy rule base and membership functions. Furthermore, genetic algorithms are introduced to optimize the parameters of the fuzzy controller, thereby significantly improving control accuracy and adaptability. Simulation results demonstrate that the designed fuzzy control system maintains excellent stability and rapid response characteristics under varying load conditions and parameter uncertainties. Compared with traditional PID control methods, the overshoot is reduced by approximately 25%, and the settling time is shortened by about 30%. Additionally, experimental verification further confirms the feasibility and superiority of the proposed scheme in practical applications.
