World Medical &Health Policy, EarlyView.ABSTRACT The study by Morshed‐Behbahani et al. highlights that financial barriers are not the sole obstacle to accessing infertility treatment. To ensure equal access for all, infertility treatment should be regarded as a universal human right, with the public sector assuming responsibility for its provision.

Parameters Optimization Of Model Predictive Control [PDF]
, 2013 模型预测控制是一种基于预测模型的先进控制算法，在工业过程中得到广泛的应用。与传统的控制算法相比，模型预测控制因为采用启发式优化，在性能参数的选择上更加灵活。一般可以通过选择预测时域、控制时域、加权系数等参数来优化系统的稳态性能。然而，由于缺乏系统的参数优化方法，一定程度上导致了控制器参数选择的盲目性。针对上述问题，本文研究并提出新的模型预测控制的参数优化方法，分别从系统的瞬态性能和抗干扰性能的角度，实现约束松弛参数和加权系数优化，充分发挥系统潜能。 首先 ...
