电动执行机构是连接控制器与执行器(阀门)的部件,从控制出来的是离散信号,经零阶保持器后成为一个方波 信号,值都是阶跃跳动,而阀门的实际工作是有一定的行程时间的,即实际上阀门是不可能实现阶跃跳动的,故此需要一个电动执行器,将控制器的阶跃信号变为连续变化信号,假定阀门的行程时间与阀门开度变化成正比。(Electric Actuator is connected controller and actuator (valve) parts, from the control out of the discrete signal by zero-order cage became a square wave signal, values are step-beating, but the actual work of the valve there is a certain amount of travel time, that is, in fact the valve can not be achieved step beat, and therefore need an electric actuator, the controller of the step change in the signal into a continuous signal, assuming that the valve and the valve travel time changes in direct proportion to the door opening.)

Hybrid PV-wind generation shows higher
availability as compared to PV or wind alone. For rural
electrifications, researches are focused on hybrid power system
which provides sustainable power. The variable voltage and
frequency of the self excited induction generator (SEIG) is
rectified through Vienna rectifier (three switches) to the required
D.C voltage level and fed to common D.C bus. The variable output
voltage of PV module is controlled by DC/DC converter using
proposed fuzzy logic controller and fed to common D.C bus. The
DC bus collects the total power from the wind and photovoltaic
system and used to charge the battery as well as to supply the A.C
loads through inverter. A dynamic mathematical model and
MATLAB simulations for the entire scheme is presented. Results
from the simulations and experimental tests bring out the
suitability of the proposed hybrid scheme in remote areas.
