In this paper, on based research of PCH control of AC motors by research group, speed sensorless control is introduced, then speed estimation of AC motor is realized.
Methods: A model of experimental PCH induced acute hemorrhagic necrotizing pancreatitis(AHNP) was induced by retrograde injection of 5% sodium taurocholate into the pancreatic duct.
方法:应用5 %牛磺胆酸钠逆行胰胆管注射诱发大鼠AHNP并发脑组织损害模型。
First, using the PCH systems「 structural properties and the systems」 zero-state detectability, a new control design method is developed.
首先,利用哈密顿系统的结构特性和零状态可检测性,得到了一种新的设计方法。
PCH offers a feasible option for liver transplantation in those patients with complex thrombosis of the mesenteric and portal circulation.
PCH是肝移植后肠系膜和门经脉循环中出现符合血栓后的可行性治疗选择。
We analyzed the characteristics of the PCH model of ac machine. These included: energy balance, dissipation, passivity etc.
