Control of Electrical Drives Articles: Closed Loop Speed Control of Multi Motor Drives : When mechanical part of the load is of large physical dimension it becomes desirable to share…
Phase Locked Loop Control(PLL): A PI controller ideally should provide perfect speed regulation. However, due to imperfections in sensing and control circuits, the closed-loop schemes described earlier can at best…
Current Limit Control of Drives: Current Limit Control of Drives scheme of Fig. 3.3 is employed to limit the converter and motor current below a safe limit during transient operations.…
Automatic Frequency Control Block Diagram: Automatic frequency control: As previously we see, the heart of an AFC circuit is a frequency-sensitive device, such as the phase discriminator, which produces a…
Delayed Automatic Gain Control: Delayed Automatic Gain Control: Simple AGC is clearly an improvement on no AGC at all, in that the gain of the receiver is reduced for strong…
Working Principle of Automatic Gain Control: Working Principle of Automatic Gain Control is a system by means of which the overall gain of a radio receiver is varied automatically with…
Temperature Control System: Before going to study the temperature control system, let us see the block diagram of microprocessor based process Temperature Control System. It is capable of controlling more…
Speed Control of DC Motor: The Fig. 15.38 shows the analog approach to control the Speed Control of DC Motor. A tachometer is used to get the information about the…
