... motor. For example, in order for many motors to spin at half of their speed, they require an input of 50% of their maximum operational voltage. This can be easily done at a lab bench, however in actual use, many devices' power supply systems are designed to provide only constant voltage outputs.1 Th ...

Three-Phase Current Measurement
... Advanced motor control algorithms such as field-oriented control (FOC) and direct torque control (DTC) require sensing of motor phase currents. To reduce the number of sensors and overall cost of the solution, the phase currents can be measured by means of low-cost shunt resistors with a simple inte ...

Control of a DC/DC Converter Using FlexPWM`s Force
... The configuration described in the previous section allows software control of the shift between the two PWM pairs, and thus of the output voltage of the DC/DC converter. The force-out logic of the FlexPWM should now be configured to automatically and immediately complement the second PWM pair in ca ...

Distributed control system
A distributed control system (DCS) is a control system for a process or plant, wherein control elements are distributed throughout the system. This is in contrast to non-distributed systems, which use a single controller at a central location. In a DCS, a hierarchy of controllers is connected by communications networks for command and monitoring.Example scenarios where a DCS might be used include: Chemical plants Petrochemical (oil) and refineries Boiler controls and power plant systems Nuclear power plants Environmental control systems Water management systems Metallurgical process plants Pharmaceutical manufacturing Sugar refining plants Dry cargo and bulk oil carrier ships Formation control of multi-agent systems
