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 the difference between feedback control feed forward control and concurrent control?
1) Use ONLY feedforward control if:The physics/chemistry of the application are well knownYou can easily measure or calculate the variables in the equationsThere are no significant process disturbancesThe accuracy of the measurements used is an order of magnitude better than the application specifications2) Use ONLY feedback control if:Significant un-modeled process disturbances existYou cannot measure or calculate variables in the equations describing the physics/chemistry of the application.The accuracy of the measurements used is NOT an order of magnitude better than the application specifications.3) Use both when:The physics/chemistry of the application are well knownYou can easily measure or calculate the variables in the equationsThe accuracy of the measurements used is on the order of the application specificationsYou want to prevent saturation of the controller integratorsYou want to improve trajectory tracking, but 2nd and higher order dynamics in the plant limit your controller bandwidth
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.
Which structure of a feedback system receives output from the control center?
The structure that receives output from the control center in a feedback system is typically the effector. The effector is responsible for carrying out the response dictated by the control center to maintain homeostasis or achieve the desired outcome.
When the body changes an internal condition back to it's normal state it is called feedback?
Feedback control is the process by which a system's output is monitored and used to adjust the system's input. This mechanism allows the body to regulate internal conditions within a narrow range, maintaining homeostasis. Negative feedback is a common type of control system where the system responds in a way that reduces the discrepancy between the desired and actual output.
What is a control mechanism that responds to a stimulus by decreasing its intensity called?
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.
What are types of control in business organization?
· Feedback control · Concurrent control · Feedforward control
What is the advantage of feedforward control?
One major advantage of feedforward controls is that it prevents large disturbances in your output
Is feedforward control also known as preliminary control?
Sometimes feedback controls are called preliminary controls, they are accomplished before a work activity begins. They make sure that proper directions are set and that the right resources are available to accomplish them
What is the basic control process?
It begins with the establishment of clear standards of performance, involves a comparison of performance to those standards, takes corrective actions, if needed, to repair performance deficiencies; is a dynamic, cybernetic process, and uses three basic methods-- feedback control, concurrent control, feedforward control.
What type of control feed forward concurrent or feedback do you think would have been most useful in this situation?
In this situation, feedback control would likely be the most useful. Feedback control allows for adjustments based on the outcomes of previous actions, enabling continuous improvement and problem-solving. This approach helps identify and correct errors after they occur, ensuring that future processes are more effective. While feedforward control can help anticipate issues, feedback is essential for learning from past experiences and refining processes.
Which kind of control takes place after the actual work has been carried out?
Feedforward.
What is the Advantage and disadvantage of feedforward control?
One major advantage of feedforward controls is that it prevents large disturbances in your output. A disadvantage is that it may not account for all potential disturbances in the input, leading to large disturbances in the output.

What is the difference between cybernetic and non cybernetic control?
Cybernetic controls include Routine Expert Trial-and-error Learning takes place here through feedback and feedforward Non-cybernetic controls include Intuition Judgement Power and politics Learning does not take place as objectives are ambiguous, outputs are not measurable and the effects of intervention are unknown
What has the author Michael J Doherty written?
Michael J. Doherty has written: 'Input shaping to reduce solar array structural vibrations' -- subject(s): Vibration damping, Feedforward control, Pointing control systems, Shape control, Structural vibration
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.
