Control reconfiguration — is an active approach in control theory to achieve fault tolerant control for dynamic systems [1]. It is used when severe faults, such as actuator or sensor outages, cause a break up of the control loop, which must be restructured to prevent… … Wikipedia
Control valves — are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a setpoint to a process variable whose value is… … Wikipedia
Control variates — The control variates method is a variance reduction technique used in Monte Carlo methods. It exploits information about the errors in estimates of known quantities to reduce the error of an estimate of an unknown quantity.[1] Contents 1… … Wikipedia
control theory — Field of applied mathematics relevant to the control of certain physical processes and systems. It became a field in its own right in the late 1950s and early 60s. After World War II, problems arising in engineering and economics were recognized… … Universalium
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
