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.
Does voluntary responses control the activity of glands?
The response of your glands is involuntary and controlled by a negative feedback system.
What are examples of feedback loops in are body?
example of negative feedback example of negative feedback
How are plant hormones transported?
gibberellin by feedback control and abscisic acid by xylem an phloem transport gibberellin by feedback control and abscisic acid by xylem an phloem transport
What is the role of the feedback in a system?
The role is to monitor the input, process, and output so that the system can adjust itself to meet the goal.

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.
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
The basic type of control system in the body is the?
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.
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
What allows negative feedback to a control system?
the system has parts that sense the amount of output
What is the endocrine definition of self-regulating?
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and positive feedback.
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
