Control theory deals with the control of dynamical systems in engineered processes and machines. The objective is to develop a control model for controlling such systems using a control action in an optimum manner without delay or overshoot and ensuring control stability.
A programmable logic controller (PLC) or programmable controller is an industrial digital computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. In some countries, ATC plays a security or defensive role, or is operated by the military.
The Nintendo GameCube is a home video game console released by Nintendo in Japan and North America in 2001 and in PAL territories in 2002. The GameCube is Nintendo's entry in the sixth generation of video game consoles and is the successor to their previous console, the Nintendo 64. The GameCube competed with Sony's PlayStation 2 and Microsoft's Xbox.
A proportional–integral–derivative controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an error value as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms, hence the name.
A game controller, gaming controller, or simply controller, is an input device used with video games or entertainment systems to provide input to a video game, typically to control an object or character in the game. Before the seventh generation of video game consoles, plugging in a controller into one of a console's controller ports were the primary means of using a game controller, although since then they have been replaced by wireless controllers, which do not require controller ports on the console but are battery-powered. USB game controllers could also be connected to a computer with a USB port. Input devices that have been classified as game controllers include keyboards, mouses, gamepads, joysticks, etc. Special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers.
Air traffic control specialists, abbreviated ATCS, are personnel responsible for the safe, orderly, and expeditious flow of air traffic in the global air traffic control system. Usually stationed in air traffic control centers and control towers on the ground, they monitor the position, speed, and altitude of aircraft in their assigned airspace visually and by radar, and give directions to the pilots by radio. The position of air traffic controller is one that requires highly specialized knowledge, skills, and abilities. Controllers apply separation rules to keep aircraft at a safe distance from each other in their area of responsibility and move all aircraft safely and efficiently through their assigned sector of airspace, as well as on the ground. Because controllers have an incredibly large responsibility while on duty and make countless real-time decisions on a daily basis, the ATC profession is consistently regarded around the world as one of the most mentally challenging careers, and can be notoriously stressful depending on many variables. Many controllers, however, would cite high salaries, and a very large, unique, and privileged degree of autonomy as major advantages of their jobs.
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.
Model–view–controller is a software design pattern commonly used for developing user interfaces that divides the related program logic into three interconnected elements. This is done to separate internal representations of information from the ways information is presented to and accepted from the user.
The State Controller of California is the chief financial officer of the U.S. state of California. The post has broader responsibilities and authority than the California State Treasurer.

The original NES controller could be inserted inside by snapping open the back. The Super Controller still allowed the player to use the original A, B, Start, and Select buttons on the NES controller; the only difference was an arcade stick-like knob that fit over the D-pad of the original NES controller.
The Jammer is an arcade-style controller for the Nintendo Entertainment System made by Beeshu. It is a clone of Nintendo's officially licensed arcade controller, the NES Advantage.

The Sixaxis was succeeded by the DualShock 3, an updated version of the controller that, like the DualShock and DualShock 2 controllers, incorporates haptic technology – also known as force feedback. A Sixaxis controller can also be used with Sony's PSP Go via Bluetooth after registering the controller on a PlayStation 3 console.
The GameCube controller is the standard game controller for the GameCube home video game console, manufactured by Nintendo and launched in 2001. As the successor to the Nintendo 64 controller, it is the progression of Nintendo's controller design in numerous ways. The contentious M-shaped design of its predecessor was replaced with a more conventional handlebar style controller shape; a second analog stick was added, replacing the C buttons with a C stick and the X and Y face buttons, last seen on the Super Nintendo controller, were reintroduced; the shoulder buttons were changed to hybrid analog triggers. A wireless variant of the GameCube controller known as the WaveBird was released in 2002.

PlayStation Move is a motion game controller developed by Sony Computer Entertainment. Initially released in 2010 for use with the PlayStation 3 video game console, its compatibility was later expanded to its successor, the PlayStation 4, in 2013, its PlayStation VR platform in 2016 and the PlayStation 5 in 2020. Conceptually similar to Nintendo's Wii Remote and Microsoft's Kinect, its function is based around controller input in games stemming from the actual physical movement of the player. The Move uses inertial sensors in the wand to detect motion while the wand's position is tracked using a PlayStation Eye or PlayStation Camera. The device was generally well-received by critics, but has not quite met Sony's goals for integration into the market.
