Closed Loop Control - an overview | ScienceDirect

The closed-loop control of a system offers the possibility to dynamically adjust its inputs in order to follow a reference set point, and to reduce the effect of the perturbations from the system's environment. Indeed, we have seen that nonlinear behavior can occur, like the pull-out phenomenon for instance. Closed-loop control is achieved by

There are two common classes of control action: open

There are two common classes of control action: open loop and closed loop. In an open-loop control system, the control action from the controller is independent of the process variable. An example of this is a central heating boiler controlled only by a timer. The control action is the switching on or off of the boiler.

The Closed System | | DIY Radiant Floor Heating |

Introduction This approach utilizes a dedicated heat source for the radiant floor. The fluid in a closed system is re-circulated around and around in a completely closed loop. There is no connection whatsoever to the domestic water supply. The main advantage to this system lies in the fact that, being closed, anti-freeze instead of water []

An automatic closed-loop control system of boiler

A system for automatic closed-loop control of drum boiler heat load for combined joint and separate combustion of blast-furnace, coke, and natural gases under the conditions of randomly changed flow rates of blast-furnace and coke gases is considered. For achieving more efficient operation of the automatic control system, it is proposed to introduce circuits for compensating random
