motor_operator
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.)
