... The device is aimed at substituting conventional triac phase angle control drives. Circuit is capable of supplying single-phase a.c. induction motor (or general a.c. inductive/resistive load) with varying a.c. voltage at the start. Similar to triac control, voltage applied to load is varied from zer ...

Fuzzy Logic Speed Controllers Using FPGA Technique For Three
... Motors, solenoids, transformers, and even some resistive heaters have inductive components as apart of their impedance. The effect of this reactance is that the rms-to-average-current ratio is lowered. Higher average current can be passed through the SCR. With an inductive load , current flow is mai ...

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
