Types of Steel Rolling Mills: Types of Steel Rolling Mills are either hot rolled or cold rolled. These may be either reversing type or continuous type. The motors used for…
Root Locus Plot: In the electrical drives employing closed loop control techniques, it is often necessary to investigate the effects of changing the parameters of the system on its stability.…
Stability from Bode Plot of Open Loop Transfer Function: The Nyquist criterion details how the open loop polar plot can be used for establishing. the stability of a closed loop…
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…
Frequency Response Transfer Function: The previous sections- show that with the time response of a system, even though it is a direct method of analysis, the adjustment of the parameters…
Ward Leonard Drive Transfer Function: In the classical Ward Leonard Drive Transfer Function, the dc drive motor having constant excitation is supplied from a variable voltage generator, as shown in…
Features of Electric Drive System: Before applying advantageously the control principles to electric drive systems to adjust or improve their behaviour as a special case of control problem, it is…
Introduction Control Techniques in Electric Drives: An electric drive is a well established industrial drive as it has several adÂvantages and special features. Its Control Techniques consists in starting, speed…
