摘    要:为了提高PWM整流器的动态性能,提出了一种新型的提高PWM整流器动态性能的模型预测直接功率控制(MPDPC)策略。传统MPDPC方案中,由于有功功率和无功功率将统一由单一成本函数控制,若2个控制目标中任何一个控制权重集中,则会导致相互干扰,影响控制动态性能。因此,设计了可重构权重因子成本函数,通过重新配置权重因子,降低了控制量之间的相互干扰,使得系统的动态性能得到优化。最后,对比试验结果验证了新型MPDPC方案的优势。

关 键 词:变换器  直接功率控制  模型预测控制  成本函数

Abstract:In order to improve the dynamic performance of PWM rectifier,a new model predictive direct power control(MPDPC)strategy was proposed to improve the dynamic performance of AC/DC converters.In the traditional MPDPC scheme,since the active power and the reactive power are controlled by a single cost function,if one of the two control targets have a centralized control weight,it will cause mutual interference and affect the control of dynamic performance.Therefore,the reconfigurable weight factor cost function was designed.By reconfiguring the weight factor,the mutual interference between the control variables was reduced and the dynamic performance of the system was optimized.Finally,the comparative test results verify the advantages of the new MPDPC solution.
Keywords:converter  direct power control  model predictive control  cost function
