淮河流域高质量发展与流域生态环保密切相关,需要良好生态环境给予支撑。虽然淮河流域生态环保已基本实现有法可依,但其生态环境质量仍有待提升。现行淮河流域生态环保法治仍存在立法滞后、立法偏差、治理体制机制不完善等问题,无法满足淮河流域高质量发展的需求。完善淮河流域生态环保法治建设是实现淮河流域高质量发展的前提与保障,符合生态文明理念与保障人权的基本思想,也能很好地满足淮河流域生态环境保护的特殊性需求。针对淮河流域生态环保法治不健全的现状及其内在原因,应当加快构建以淮河流域专门立法为核心的法治体系,以体制化改革强化淮河流域生态环保治理措施,完善生态补偿、公众参与等生态环保配套制度,实现淮河流域生态与经济、社会的高质量发展。

模型预测控制方法已经被广泛应用于内置式永磁同步电机(IPMSM)的控制之中,传统模型预测控制方法由于候选电压矢量数量有限,在电机运行过程中会产生较大的电流和转矩谐波。为了增加候选电压矢量数量,提出了构建虚拟电压矢量的方法。但是在应用虚拟矢量调制方法时,系统计算的负担会随虚拟矢量数量的增加而增加,因此控制效果会受到系统计算能力的限制。针对此问题,该文提出了一种新型的虚拟电压矢量调制方法,首先将电压扇区进行细分来增加虚拟电压矢量的数量,然后通过对指令电压矢量坐标进行标幺化处理的方法求得其角度,最后从基础和虚拟电压矢量之中由角度搜索选出最优电压矢量。在该方法中,系统的计算量大小与虚拟电压矢量的数量无关,因此可以在不增加系统计算负担的情况下提升系统的控制性能。实验结果表明,与虚拟矢量数量受到限制的虚拟矢量预测控制方法相比,该方法有效减少了三相电流谐波含量,并且减少了控制算法的执行时间。
