set-point (SP). There are two common classes of control loop: open loop and closed loop. In an open-loop control system, the control action from the controller...

The open-loop gain of an electronic amplifier is the gain obtained when no overall feedback is used in the circuit. The open-loop gain of many electronic...

In control theory, an open-loop controller, also called a non-feedback controller, is a control loop part of a control system in which the control action...

A closed-loop controller or feedback controller is a control loop which incorporates feedback, in contrast to an open-loop controller or non-feedback...

an open-loop model is called "open-loop equilibrium". Open loop models are more tractable, which is why they are sometimes preferred to closed-loop models...

their product G ( s ) H ( s ) {\displaystyle G(s)H(s)} is called the open-loop transfer function. We define an intermediate signal Z (also known as error...

directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling...

there are two types of control loop: open-loop control (feedforward), and closed-loop control (feedback). In open-loop control, the control action from...

Sources differ on whether an open loop or U-shaped curve in a rope qualifies as a bight. Ashley (1944) treats bights and loops as distinct, stating that...

many systems with feedback loops cannot be shoehorned into either type, and this is especially true when multiple loops are present. When there are only...

some of the parallel streams may have very weak channel gains. In an open-loop MIMO system with N t {\displaystyle N_{t}} transmitter antennas and N...

there are two types of control loop: open-loop control (feedforward), and closed-loop control (feedback). In open-loop control, the control action from...

control system theory, loop gain is the sum of the gain, expressed as a ratio or in decibels, around a feedback loop. Feedback loops are widely used in electronics...

create the final figure-8 loop knot. A noose can refer to any sliding loop in which the loop tightens when pulled. An open loop is a curve in a rope that...

frequency where the open-loop gain flips sign f180 does not change with a change in feedback factor; it is a property of the open-loop gain. The value of...

reflexes or long-loop reflexes are reflex arcs which involve more than a single synaptic connection in the spinal cord. These loops may include cortical...

Open-loop control works as long as the forces are kept small enough and speeds are not too great. On commercial metalworking machines, closed-loop controls...

There are three types of control systems: open loop, feed-forward, and feedback. An example of a pure open loop control system is manual non-power-assisted...

to below the open-loop gain, the gain–bandwidth product of the closed-loop amplifier will be approximately equal to that of the open-loop amplifier. "The...
