图1. 开环 vs. 闭环运动控制。 开环系统 开环绝不直接意味着粗糙。即使廉价的开环器件也可以实现非常精细的增量运动。开环压电器件足以实现纳米级的增量运动,例如Picomotor开环系统在不依靠编码器的情况下,可以推断一个运动装置的大致位置。 对于压电器件而言,由施加的电压可直接得出当前位置。然而,由于常见压电材料...
On the surface, open-loop systems seem to be more efficient than closed-loop systems. One reason for that is that water transfers heat more readily than the closed-loop antifreeze mixture because it’s more conductive. Also, if you have a large supply of groundwater, you’ll have a more ...

Traditional methodology for optimizing and tuning PID loops (excluding `trial-and-error') rely on `open-loop' tests,whereby the loop is placed in manual mode and the controller output is moved, usually in a step-wise fashion. The issues with this `step' test are numerous, primarily that th...

What is the main advantage of working with a closed loop and an open loop wet blaster? On a closed loop, you do not need a supply of running water to operate it. A closed loop wet blaster cabinet needs no external water connection or drain to operate. ...
