One application of feed back control is where the speed of a motor has to be maintained at a certain RPM and the load it drives is variable. Feedback from the load tells the VFD (Variable Frequency Drive) motor controller what to do. As the load drags the motor speed down the feedback unit sends a electrical impulse to the VFD to increases the speed of the motor. As the load drops off the feedback unit sends a electrical impulse to the VFD to decreases the speed of the motor. These interactions keep the motor RPM at a constant speed. This is a very simplified version of what happens.
The response of your glands is involuntary and controlled by a negative feedback system.
example of negative feedback example of negative feedback
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.
The role is to monitor the input, process, and output so that the system can adjust itself to meet the goal.
decays
A: feedback is not an application but rather is a must to keep a system or amplifier stable in the linear regions
When there is no feedback to control its output.
A: It is any system where there is negative feedback to control its behavior
open loop
nervous system. It regulates and coordinates all body functions by sending electrical signals between different parts of the body. Its main components are the brain, spinal cord, and nerves.
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
the system has parts that sense the amount of output
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and 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.
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
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
The three main components of the feedback loop are; soliciting information, collecting information and compiling the information into a report. The last component of the feedback loop is implementation of the information
