What is control system Short answer?

What is control system Short answer?

What is control system? A system consists of a number of components connected together to perform a specific function . In a system when the output quantity is controlled by varying the input quantity then the system is called control system.

What is control system Mcq?

Explanation: Control System is a system in which the output is controlled by varying the input.

What are the 5 basic elements of a control system?

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.

Who is the father of control system?

Nels Tyring, commonly considered the father of the profession of control system integration, passed away after a long bout with cancer in December.

Where is control system used?

Control Systems are used in domestic applications, general industry, military and virtually every modern vehicle in the world. Control Systems are very common in SCADA and Industrial Automation systems. Control Systems are used in Industrial Automation to regulate how devices operate in real time.

Why control system is needed?

Control system engineering ensures that there is a strategic method to improving productivity and enhancing the best practices of your company. You want to eliminate the redundant manual controls and reduce human errors that could cost you a significant amount of money.

What is DCS plant?

A distributed control system (DCS) is a platform for automated control and operation of a plant or industrial process. A DCS combines the following into a single automated system: human machine interface (HMI), logic solvers, historian, common database, alarm management, and a common engineering suite.

What are the main elements of control?

Elements of a good Control System

  • 1) Feedback. Feedback is the backbone of all control systems. …
  • 2) Control must be objective. …
  • 3) Prompt reporting of deviations. …
  • 4) Control should be forward-looking. …
  • 5) Flexible controls. …
  • 6) Hierarchical suitability. …
  • 7) Economical control. …
  • 8) Strategic control points.

How many types of control are there?

Three basic types of control systems are available to executives: (1) output control, (2) behavioural control, and (3) clan control. Different organizations emphasize different types of control, but most organizations use a mix of all three types.

What are the 3 components of control system?

Abstract. The constitution of a closed-loop control system is discussed in chapter 1; the basic system is defined in terms of three elements, the error detector, the controller and the output element.

What are the types of control system?

There are two types of control systems namely:

  • Open loop control systems (non-feedback control systems)
  • Closed loop control systems (feedback control systems)

What are the classification of control system?

Control Systems can be classified as open loop control systems and closed loop control systems based on the feedback path. In open loop control systems, output is not fed-back to the input. So, the control action is independent of the desired output.

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 a control model?

Control models are models deployed in software engineering that are concerned with the control flow between the sub- systems. They are distinct from the system decomposition model. They are classified into centralized and event-based models. Centralized models are classified into call-return and manager model.

What is a controller in control system?

In control systems, a controller is a mechanism that seeks to minimize the difference between the actual value of a system (i.e. the process variable) and the desired value of the system (i.e. the setpoint). Controllers are a fundamental part of control engineering and used in all complex control systems.

What are the devices of control?

Types of Control Devices and Controllers

  • Access Control Systems. …
  • Flow Controllers. …
  • Level Controllers. …
  • Pressure Controllers. …
  • Programmable Logic Controllers. …
  • Control Method. …
  • Input Types. …
  • Output Types.

What is output in control system?

However, in a control system, input are either setting a desired values or actions that stimulate the system to do a specific task. In contrast, outputs are the actual result or response in a control system.
