The technique made full use of the characteristic of PR controller which can realize zero steady-state error in AC input signal in stationary frame. In the method, the active and reactive current component in the vector control strategy were transformed in the stationary frame to achieve the objective of keeping the DC-link voltage constant, adjusting the power factor and decoupling the active and reactive power. Compared with conventional double close-loop proportional integral controller, the PR technique is better in harmonic compensation without the complex rotating frame transformation and the couple or feedback voltage which is easily influenced by temperature and circuit parameters. The control algorithm is easy to be realized while the robustness and power quality is improved.
该方法充分利用了PR控制器能够在静止坐标系下对交流输入信号无静差控制的优势,将矢量控制策略下的有功电流和无功电流分量转换到静止坐标系下进行调节,实现网侧变换器维持直流电压稳定和调节功率因数的控制任务和双馈电机有功、无功功率的解耦控制,与传统的双闭环PI控制相比,该策略无需繁琐的坐标旋转变换,不存在受温度及电路参数影响的耦合项和前馈补偿项,且易于实现对系统低次谐波电流的补偿,减小了控制算法实现难度,提高了控制系统的鲁棒性和电网电能质量。

Results showed:(1) The airway responsiveness of smoke control group was higher than that of normal control group, the airway responsiveness of smoke + exercise group was lower than that of smoke control group;(2) Plasma level of cortisol determined immediately after exercise was higher than that determined before exercise, no significant difference occurs between that determined next day morning after all exercise finished in contrast to that determined before exercise;(3) HE staining showed, there was severe chronic pulmonary inflammatory response in smoke control group, which was reduced in the smoke + exercise group;(4) chronic cigarette smoke downregulated the protein and mRNA expression of BKca in smooth muscles of bronchi and bronchioli, exercise increased the mRNA expression of BKca;(5) chronic cigarette smoke downregulated the protein and mRNA expression of Kv1. 5 in smooth muscles of bronchi and bronchioli, exercise increased both the protein and mRNA expression of Kv1. 5 in contrast to smoke control group in bronchioli and did not effect the expression of Kv1. 5 in bronchi;(6) chronic cigarette smoke induced upregulation of FIZZ1/RELMα in bronchial smooth muscle cells, exercise decreased these effect.
结果:(1)吸烟对照组的气道反应性明显增高,吸烟加运动应激可明显降低大鼠的气道反应性;(2)吸烟运动组运动后血浆皮质醇浓度明显高于运动前,但全部运动结束后次日晨测定的血浆皮质醇浓度与运动前无明显差异;(3)HE染色显示,吸烟对照组肺组织出现明显的慢性炎症反应,吸烟加运动应激组比吸烟对照组炎症反应轻;(4)慢性吸烟可降低大鼠大气道和小气道BKca mRNA和蛋白表达,而吸烟加运动应激可使BKca mRNA表达上调,但对小气道的蛋白表达无影响;(5)慢性吸烟可降低大鼠大气道和小气道Kv1.5蛋白和mRNA表达,在小气道吸烟加运动应激可减轻这种作用,大气道则无作用;(6)吸烟使支气管平滑肌的FIZZ1/RELMα蛋白表达明显增强,而吸烟加运动组的RELMα蛋白及mRNA均明显减弱。
