Control of DC Drives Using Microprocessors: The dc motors fed from thyristor converters for variable speeds are being exÂtensively used in general industrial applications. A dual converter, which is a…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists…
Hardware Systems Versus Microprocessor Control: The Hardware Systems Versus Microprocessor Control control of electric drives offers the following advantages when compared to the dedicated hardware control. As has already been…
Turbocompressors: The turbocompressors and blowers in the industry require drives rated up to 40 MW. Drives of large rating are also required in steel industry blast furnace blowers in natural…
Centrifugal Pump Load: Centrifugal Pump Load are used as boiler feed pumps and for pumping water in water pipe lines. The former must be adapted to the variable output of…
Cement Mill Process: The Cement Mill Process has different Stages in Cement Production and they are The raw materials of Cement Mill Process are lime and silica. Alumina and ferric…
Routh Hurwitz Criterion: The Routh Hurwitz Criterion states that the system is stable if the Routh table has no negative elements in the first column. The roots of the characteristic…
Reversible Drives using Choppers: Using two quadrant choppers a reversible drive can be achieved, because this combination allows reversal of both current and voltage of the motor termiÂnals. We can…
