摘要:
针对三相 Vienna 整流器控制系统计算、采样等延时引起的功率误差问题,提出一种两步预 测直接功率控制( DPC) 算法。基于无差拍控制原理设计内环直接功率控制器,推导两相静止坐标 系下控制参考电压矢量公式,并结合二阶拉格朗日差值法估算 k + 2 时刻有功功率给定值,提高功 率预测精度。同时为提高电压外环响应速度和稳定精度,构建以直流侧电压平方为反馈量的滑模 控制器( SMC) 。最后搭建 10 kW 三相 Vienna 整流器仿真模型与实验平台对所提算法进行验证。 仿真和实验结果表明: 无差拍预测直接功率与滑模控制相结合的算法不仅可以有效减小输入侧电 流谐波含量及功率脉动,而且可以提高三相 Vienna 整流器的动态响应速度和抗干扰性能。
Abstract:
In order to eliminate the power error caused by computation and sampling delay in three-phase Vienna rectifier,the two-step predictive direct power control ( DPC) algorithm was presented. The direct power controller was designed for the inner-loop power based on deadbeat control principle,and then the reference voltage equation was deduced in the two-phase stationary coordinate system. The reference active power value was accurately estimated using the reference voltage equation and the second-order Lagrangian interpolation method. Additionally,to improve the response speed and stability of the outer-loop voltage,a sliding mode control ( SMC) was deduced with the square of the DC-side voltage as the control feedback value. Finally,a three-phase Vienna rectifier system was established to verify the proposed algorithm based on 10 kW platform. Both simulation and experimental results were utilized to prove that the PDPC-SMC algorithm not only reduces power ripples and current harmonics,but also enhances the dynamic response speed and anti-interference ability.
