Hysteresis — Not to be confused with Hysteria. Fig. 1. Electric displacement field D of a ferroelectric material as the electric field E is first decreased, then increased. The curves form a hysteresis loop. Hysteresis is the dependence of a system not… … Wikipedia
Control system — For other uses, see Control system (disambiguation). A control system is a device, or set of devices to manage, command, direct or regulate the behavior of other devices or system. There are two common classes of control systems, with many… … Wikipedia
Control relay — A control relay is an electromechanical device which activates one or more switches according to the current through a coil not connected to the switches. The thyristor is a semiconductor device which carries out similar functions.A relay is… … Wikipedia
Direct torque control — (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors. This involves calculating an estimate of the motor s magnetic flux and torque based on the measured… … Wikipedia
Chaotic hysteresis — A nonlinear dynamical system exhibits chaotic hysteresis if it simultaneously exhibits chaotic dynamics (chaos theory) and hysteresis. As the latter involves the persistence of a state, such as magnetization, after the causal or exogenous force… … Wikipedia
Bang–bang control — A water heater that maintains desired temperature by turning the applied power on and off (as opposed to continuously varying electrical voltage or current) based on temperature feedback is an example application of bang–bang control. Although… … Wikipedia
Proportional control — A proportional control system is a type of linear feedback control system. Two classic mechanical examples are the toilet bowl float proportioning valve and the fly ball governor. The proportional control system is more complex than an on off… … Wikipedia
Bang-bang control — In control theory, a bang bang controller is a controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary… … Wikipedia
Deadband — A deadband (sometimes called a neutral zone) is an area of a signal range or band where no action occurs (the system is dead). Deadband is used in voltage regulators and other controllers. The purpose is common, to prevent oscillation or repeated … Wikipedia
Electromagnetic clutch — Electromagnetic clutches operate electrically, but transmit torque mechanically. This is why they used to be referred to as electro mechanical clutches. Over the years, EM became known as electromagnetic versus electro mechanical, referring more… … Wikipedia
