Hall circles (also known as M-circles and N-circles) are a graphical tool in control theory used to obtain values of a closed-loop transfer function from the Nyquist plot (or the Nichols plot) of the associated open-loop transfer function. Hall circles have been introduced in control theory by Albert C. Hall in his thesis. [1]
Automatic control manages a device without the need of human inputs for correction, such as cruise control for regulating a car's speed. Control systems engineering activities are multi-disciplinary in nature. They focus on the implementation of control systems, mainly derived by mathematical modeling. Because instrumentation and control play a ...
Control systems play a critical role in space flight.. Control engineering, also known as control systems engineering and, in some European countries, automation engineering, is an engineering discipline that deals with control systems, applying control theory to design equipment and systems with desired behaviors in control environments.

The Internet Archive is an American non-profit organization founded in 1996 by Brewster Kahle that runs a digital library website, archive.org. [2] [3] [4] It provides free access to collections of digitized media including websites, software applications, music, audiovisual, and print materials. The Archive also advocates a free and open ...
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.
SCCS was the dominant version control system for Unix until later version control systems, notably the RCS and later CVS, gained more widespread adoption. Today, these early version control systems are generally considered obsolete, particularly in the open-source community, which has largely embraced distributed version control systems.
Unlike the frequency domain approach, the use of the state-space representation is not limited to systems with linear components and zero initial conditions. The state-space model can be applied in subjects such as economics, [4] statistics, [5] computer science and electrical engineering, [6] and neuroscience. [7]
In September 2013, the Union Cabinet approved the establishment of NISE in 2013 as a national institute for solar energy R&D and related activities under MNRE. [2] The National Institute of Solar Energy (NISE) was established in August 2013 by the Ministry of New and Renewable Energy (MNRE) of the Government of India as an autonomous organization.
