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 known
- You can easily measure or calculate the variables in the equations
- There are no significant process disturbances
- The accuracy of the measurements used is an order of magnitude better than the application specifications
2) Use ONLY feedback control if:
- Significant un-modeled process disturbances exist
- You 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 known
- You can easily measure or calculate the variables in the equations
- The accuracy of the measurements used is on the order of the application specifications
- You want to prevent saturation of the controller integrators
- You want to improve trajectory tracking, but 2nd and higher order dynamics in the plant limit your controller bandwidth

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 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.
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
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.
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 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.
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 is the major difference between control process and process control?
Difference between control process and process control is that system control process is typically the large scale version of where process control is used.

What is the difference between feedback control and feedback measurement system?
In feedback measuring system • indication is fedback via inverse transducer, •compared with measurand and •moves on to new steady state till error is reduced to zero. Feedback control system controls relatively high power through actuator. Feedback measuring system is drawing fairly low power devices at output (indicators, inverse transducer). Feedback in measuring system•Improves accuracy in measurement •Improves Speed of measurement •Allows remote indication •Allows noncontact measurement BUT•Increases complexity of design, operation, size and cost
Reason use an op amp in a closed loop control system?
Differential Amplifier or Summing Amplifier are usually used in a closed loop control system. The error signal will be the DIFFERENCE between the setpoint value and feedback value for Differential Amplifier. Whereas for Summing Amplifier, the error signal will be the difference between the setpoint value and feedback value only if one of the value is inverted in polarity. Another reason Op Amp is used: amplify the error signal as error signals are usually very small. Hope this helps.
