In this write-up, I want to give some examples ... resistance of the LED changes or the voltage fluctuates, the result may be devastating. This is essentially an open-loop control and there ...

Both of our open-loop control system examples above could easily be converted to closed-loop systems. A more advanced light switch might take input from a photo cell, or it could poll a motion ...

Driving a light-emitting diode (LED ... on control-loop characteristics, and the capacitor type as well as the output circuit configuration is often critical. Placing the capacitor in parallel with ...

In motion control applications, you frequently hear all sorts of loops -- open ... previously with closed-loop control and Figure 1. Continuing the traveling example, assume one car after another ...

Traditionally, electrical control systems were mostly open-loop and required human operators to regulate the process variables to achieve, or maintain, the desired output. The typical sprinkler system ...

In addition, the designer can measure the control loop with one of the alternate methods ... WLED dynamic resistance and using the typical LED I-V curve as well as chip-to-chip variations in ...

For example, traditional step motor systems run in open loop control. That means the drive electronics continuously supply current to the motor whether or not the load is demanding torque.
