Closed-loop control systems are more accurate, reliable, and robust than open-loop control systems, but they are also more difficult to design and implement, and may suffer from instability or ...

Though simple, this “open loop” form of fan control has disadvantages. Since there is no feedback mechanism, speed accuracy depends entirely on mechanical tolerances of the fan. Although it may not ...

The open-loop detection model of voltage phase and amplitude based on the synchronous rotating coordinate system is established first. Then the voltage phase is linearized to control the output ...

To provide reliable real-time control in the centralized CAV control system is challenging due to the dependency on channel conditions during the transmission of control commands. The transmission ...

Electronic control logic and system components are described that are used with a venturi carburetor to accomplish the fuel metering required in a closed loop emission control system. Special open ...

The control system design of an industrial welding robot is presented. Its purpose is to automate the sealing process of a metallic cask which welds the lid of the cask on to the body. The actuation ...
