基于连续滑模算法的DCAC逆变器系统输出电压调节
Output Voltage Regulation of DC-AC Inverters based on Continuous Sliding Mode Control
本文针对受非匹配扰动的DC-AC逆变器系统输出电压调节问题,基于有限时间扰动观测器技术提出了一种有限时间连续滑模控制方法。首先,引入有限时间扰动观测器实现系统扰动及扰动导数的有限时间精确估计,而后利用扰动估计信息构造一种新的动态滑模面；为了避免抖振现象的出现,通过设计将切换项仅出现在控制变量的导数中。最后,本文给出了存在系统参数摄动环境下的DC-AC逆变器系统的输出电压调节仿真结果,仿真结果表明所提方法具有较好的鲁棒性。
continuous finite-time sliding mode control method basedon finite-time disturbance observer is designed for DC-AC inverters with matched/mismatched disturbances.First of all, a finite-time disturbance observer is introduced for the estimations of disturbances and their derivatives.And then, the estimation information of disturbances and their derivatives are utilized to construct a new dynamic sliding surface.To eliminate the chattering phenomenon of sliding mode control, the switching terms of proposed method is designed to appear only in the derivative of control.Finally, the robustness of proposed controller to parameter perturbations is demonstrated by simulation results.
