Disturbance feedback in control systems refer to the mechanisms used to minimize the impact of external disturbances on the system's output. This can involve implementing compensation techniques, filtering, or adaptive control strategies to maintain desired performance despite disturbances. The goal is to improve the system's stability and robustness to external influences.
What else can I help you with?
It is a control system that uses feedback from the process to maitain an output to a desired level?
You are describing a closed-loop control system. This system continuously monitors the output and adjusts the input to maintain the output at the desired level by using feedback from the process.
What are the concept of feedback as its relates to cybernetic and the control system?
Feedback in cybernetics refers to the process of a system receiving and responding to information about its output in order to maintain or regulate its behavior. In control systems, feedback is used to monitor and adjust the system's performance by comparing the actual output with the desired reference input. This allows for self-regulation and correction to achieve the desired outcome.
Principle of critical-point control?
In Control function of Management,Critical control point (CCP) is a point, step or procedure at which controls can be applied to the system (feedback or feedforward) and a disturbance can be prevented, eliminated or reduced to acceptable (critical) levels.
With the feedback system the transient response?
With the feedback system, the transient response refers to how the system reacts to sudden changes or disturbances. A well-designed feedback system can help to minimize transient response by adjusting the system to maintain stability and reduce oscillations. The speed and accuracy of the transient response are important factors in determining the performance of a control system.
If a response enhances the original stimulus the system is a?
positive feedback system
Feedforward feedback control?
Feedforward is a preparatory control. EX. Smelling food leads to salivation and production of stomach acid in preparation of food. OR Starting to exercise increases heart rate and breathing rate in preparation of running low on oxygen for muscles. Feedback is a control mechanism where the product of the end mechanism either enhances or inhibits the start of the mechanism Positive feedback enhances Negative feedback inhibits
What is feed-forward control?
1. Feed-forward is a term describing a kind of system which reacts to changes in its environment, usually to maintain some desired state of the system. A system which exhibits feed-forward behavior responds to a measured disturbance in a pre-defined way - in contrast with a feedback system.2. This is a control technique that can be measured but not controlled. The disturbance is measured and fed forward to an earlier part of the control loop so that corrective action can be initiated in advance of the disturbance having an adverse effect on the system response.---------------------------------------------------------------------------------------------------------------Feed Forward control is mechanism within some control systems in which information is sent ahead in time to prepare a part of a control system.

What is unregulated system?
When there is no feedback to control its output.
When an initial disturbance produces a response that exaggerates the disturbance the mechanism is called?
positive feedback.
What is loop system?
A: It is any system where there is negative feedback to control its behavior
What Control system is designed to respond to feedback?
open loop
What are the three basic components of every feedback control system?
The three basic components of every feedback control system are: the sensor (or detector) which measures the system's output, the controller which processes this information and generates a control signal, and the actuator (or final control element) which takes the control signal and adjusts the system's input to achieve the desired output.
What are the effects of feedback on time constant of control systems?
1.feedback in control system improves the speed of response2.using feedback in control system we can reduce the sensitivity of the system to parameter variation
How are negtive feedback different from positive feedback?
some feedback r insulting or inappropriate. it depend on how u sort the question. Question is on feed back system in control system. In a control system generally there is a setpoint to be achieved. Control system aims to achieve the setpoint. However due to inherent reasons, the actual keeps hovering around the setpoint. A good control system keeps the setpoint very close to the setpoint. Control system must know the actual value to make adjustment to achieve the setpoint. Actual value is fed back to the control system. This feed back is referred as negative or positive feedback. The feed back tells the control system that the actual value is lower or higher compared to set point. This is known as negative or positive feedback.
Why do you use encoder in an elevator?
Encoder is usually used to measure the speed of a motor or a conveyor and provide feedback to the control system. In this case, the encoder reads the speed of the elevator and gives feedback to its control system
What is meant by the term disturbance in a control system?
In a control system, disturbance refers to any external influence that affects the system's behavior or performance, causing it to deviate from its desired or intended state. Disturbances can include variations in environmental conditions, input signals, or disturbances applied intentionally to test the system's robustness. The control system's ability to reject or mitigate disturbances is a key factor in its performance.
