为改善带恒功率负载CPL（constant power load）Boost变换器的功率估计精度及提高变换器系统的动态性能，提出1种基于连续有限时间扰动观测器的滑模控制策略。首先，建立变换器系统的非线性数学模型，并基于精确反馈线性化技术将模型转化为布鲁诺夫斯基（Brunovsky）标准型，进而设计扰动观测器估计CPL的总功率值。引入双曲正切函数设计连续有限时间扰动观测器解决传统有限时间扰动观测器调节参数多、输出抖振大等问题。其次，对标准型设计了非奇异快速终端滑模控制器以提升变换器系统的鲁棒性，并基于李雅普诺夫（Lyapunov）理论证明了闭环系统的稳定性。最后，仿真和实验对比结果均验证了所提控制策略的正确性和优越性。

Abstract

收起

To enhance the accuracy of power estimation for a Boost converter with constant power load (CPL) and improve the dynamic performance of the converter system, a sliding mode control strategy based on continuous finite-time disturbance observer is proposed. First, a nonlinear mathematical model for the converter system is established, which is further transformed into Brunovsky canonical form using the accurate feedback linearization technique. Afterwards, a disturbance observer is designed to estimate the total power value of CPL. To address the issues related to numerous adjustment parameters and significant output buffeting in conventional finite-time disturbance observers, a hyperbolic tangent function is introduced to design a continuous finite-time disturbance observer. Second, a non-singular fast terminal sliding mode controller is designed for the canonical form to enhance the robustness of the converter system, and the stability of the closed-loop system is proved based on the Lyapunov theory. Finally, both the simulation and experimental results validated the correctness and superiority of the proposed control strategy.
