| 11. | A basic Control Loop Diagram is shown in Table 1.
|
| 12. | It has been well documented that over 35 % of control loops typically have problems.
|
| 13. | This would cause poor transient response in the control loop due to low phase margin.
|
| 14. | The Control Loop Diagram provides a vehicle for the CFA Loop to be used effectively.
|
| 15. | For each control loop to run optimally, identification of sensor, valve, and tuning problems is important.
|
| 16. | This control loop is designated the force-rebalanced mode.
|
| 17. | If the control loop is not properly designed and tuned, the process runs below its optimum.
|
| 18. | Another method used in control loop theory uses Bode plots of gain and phase vs . frequency.
|
| 19. | The controllers can be freely parameterized and can thus be adapted to any type of control loop.
|
| 20. | Allosteric regulations are a natural example of control loops, such as cell's ability to adjust enzyme activity.
