In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.

另外，为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差，本文在无差拍控制器的基础上，又提出了基于无差拍和重复控制的复合电流控制器。

Firstly, based on literature review and qualitative surveys, the modified risk factors that affecting the effect of hypertension management in the underdeveloped rural area were identified, the specific questionnaire and SIPHF were developed, and the first cross-sectional study was conducted. Secondly, the surveyed population were then divided into intervention group and control group, and periodic health education and following up were conducted to the intervention group for six months; Thirdly, the second cross-sectional study was conducted to evaluate the effect of intervention by qualitative and quantitative survey, the indicators include the knowledge awareness rate and the right belief rate for hypertension control, and the behavior prevalence related to hypertension intervention, the disease burden, the life quality and clinical outcomes resulted from hypertension, the dynamic tendency of blood pressure and the patients\' satisfaction. And the factors related to the effect of hypertension management was evaluated; Finally, SWOT analysis was conducted to evaluate the factors affecting the intervention process and effect, based on the results of qualitative and quantitative surveys on the factors related to effect of the intervention, and to provide evidence-based suggestions for SIPHF improvement and policy-making in the underdeveloped rural area in China.

首先，在文献综述和定性调查的基础上，确认影响欠发达地区农村高血压患者管理效果的因素，设计调查问卷和高血压管理方案，并开展第一次横断面调查；其次，将调查乡镇分为试验组和对照组，对试验组患者开展健康教育和定期的随访管理，对照组患者则按常规工作对待；第三，实施规范化管理6个月后，采用定量调查和定性访谈等方式评价管理效果，通过第二次横断面调查，对试验组与对照组干预前后的危险因素变化情况及干预效果进行评估，评估内容包括患者的知识、信念和行为等与高血压防治有关的危险因素指标，及其产生的疾病负担、生活质量、临床指标、血压水平变化趋势、干预组满意度等结果指标，并分析影响高血压干预效果的因素；最后，采用SWOT分析，根据定性和定量调查结果分析该类地区今后全面开展该项工作所面临的内部和外部环境因素，并为欠发达地区农村高血压规范化管理方案完善及政策制定提供循证建议。

Sometimes it is difficult to predict and calculate the periodic orbit, so the chaotic control technology based on Washout filter is used to control chaotic phenomena of DC/DC converter.
