What is noise in control systems?
Noise Control Systems are typically used by industrial clients, environmental clients, building owners, architects, and engineers to help mitigate or lower disturbing noise levels from a sound source.
Which of the following elements is not used in an automatic control system?
In an automatic control system which of the following elements is not used? Explanation: In an automatic control system oscillator is not used because the oscillator increases the oscillations but our aim is to reduce the oscillations and hence oscillator is not used.
Which of the following is not a feature of a good control system?
1. Which of the following is not the feature of modern control system? Explanation: For a good control system the speed of response and stability must be high and for the slow and sluggish response is not used and undesirable.
What is the control action in open loop system?
One type of control system in which the output has no influence or effect on the control action of the input signal is called an Open-loop system. Hence in open-loop control system, the control action is independent of the desired output.

What is disturbance in process control?
A disturbance input is a variable that affects the process outputs but that cannot be adjusted by the control system. Inputs may change continuously or at discrete intervals of time.

Which elements is used in an automatic control system?
Feedback controls are widely used in modern automated systems. A feedback control system consists of five basic components: (1) input, (2) process being controlled, (3) output, (4) sensing elements, and (5) controller and actuating devices.
Which one of the following is the most likely reason for large overshoot in a control system?
Which one of the following is the most likely reason for large overshoot in a control system? Explanation: Large overshoot refers to the maximum peak in the response of the closed loop system and this is mainly due to the high positive correcting torque.
What is control system Mcq?
Explanation: Control System is a system in which the output is controlled by varying the input.
What is good control system?
A good control system must be objective i.e. it must be based on the scientific methods of analysis, and free from the bias, opinions and values of managers; so far as setting standards of performance and comparison of actual performance against standards are concerned.

What is the control system?
A control system is a set of mechanical or electronic devices that regulates other devices or systems by way of control loops. Typically, control systems are computerized. Control systems are a central part of industry and of automation.
What is control system in computer?
Computer control system: the computer control system consists of a high-reliability computer, various control modules with reliable properties, a motor drive unit, and various sensors, which is equipped with a software control system.
What is control system in electrical?
An electrical control system is a physical interconnection of devices that influences the behaviour of other devices or systems. A simple electronic system is made up of an input, a process, and an output. Both input and output variables to the system are signals.
What causes noise in a network?
Poor wiring techniques – Poor network wiring practices, such as using unshielded wiring, can result in additional electrical noise. Poor network design/layout – Faulty connections, loose network switches, or bad network circuitry can cause additional noise within a broadband network.
What causes electrical noise?
Electrical noise is the result of more or less random electrical signals getting coupled into circuits where they are unwanted, i.e., where they disrupt information-carrying signals. Noise occurs on both power and signal circuits, but generally speaking, it becomes a problem when it gets on signal circuits.
What is the impact of noise pollution?
Noise pollution adversely affects the lives of millions of people. Studies have shown that there are direct links between noise and health. Problems related to noise include stress related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity.
