In this paper, a robust and effective control strategy, termed high-order prescribed convergence law control (HO-PCL), is introduced for wind energy conversion systems. This innovative strategy is applied to the rotor-side converter of a doubly-fed induction generator-based wind power system and is specifically designed to address the limitations of conventional control methods, such as super-twisting algorithm (STA), integral backstepping control (IBCS), and first-order sliding mode control (1-SMC), which are prone to the chattering phenomenon. The HO-PCL strategy facilitates the independent regulation of active and reactive power, with the primary objective of enhancing the system's dynamic response by improving response time and minimizing power error. The effectiveness of the proposed control approach is evaluated through simulations conducted in the MATLAB/Simulink environment and validated via hardware-in-the-loop (HIL) testing under different operating conditions, where the performance and effectiveness are compared with that of the conventional proportional-integral (PI) controller, 1-SMC, and IBCS approaches. Simulation results show that the proposed HO-PCL approach reduces the stator current total harmonic distortion by 94.01, 91.05, and 85% compared to the PI, 1-SMC, and IBCS approaches, respectively. Additionally, it reduces response time by 99.25, 98.96, 93% relative to the same respective methods. Furthermore, the HO-PCL approach significantly improves the ripple and overshoot of power compared to other strategies. The results demonstrate its potential to advance control methodologies in wind power systems by overcoming the drawbacks of conventional techniques.
本文针对风能转换系统引入了一种稳健且有效的控制策略，称为高阶预设收敛律控制（HO-PCL）。这种创新策略应用于基于双馈感应发电机的风力发电系统的转子侧变流器，专门设计用于解决传统控制方法的局限性，如超扭曲算法（STA）、积分反步法控制（IBCS）和一阶滑模控制（1-SMC），这些方法容易出现抖振现象。HO-PCL策略有助于独立调节有功和无功功率，其主要目标是通过缩短响应时间和最小化功率误差来增强系统的动态响应。通过在MATLAB/Simulink环境中进行的仿真评估了所提出控制方法的有效性，并在不同运行条件下通过硬件在环（HIL）测试进行了验证，将其性能和有效性与传统比例积分（PI）控制器、1-SMC和IBCS方法进行了比较。仿真结果表明，与PI、1-SMC和IBCS方法相比，所提出的HO-PCL方法分别将定子电流总谐波畸变降低了94.01%、91.05%和85%。此外，相对于相同的相应方法，它将响应时间缩短了99.25%、98.96%、93%。此外，与其他策略相比，HO-PCL方法显著改善了功率的纹波和超调。结果表明，该方法有潜力克服传统技术的缺点，推动风力发电系统控制方法的发展。
