Gate Firing Converters: The firing pulse control unit constitutes the heart of any thyristor power conÂverter. The Gate Firing Converters required by the thyristors are often derived from the digital…
Speed Detector: One important factor in the closed loop control of variable speed drives emÂploying solid state converters is the Speed Detector. In the dedicated hardware control using analog components,…
Symmetrical Optimum: Symmetrical Optimum - Sometimes automatic control systems contain integrating also besides first order delay elements, proportional elements and deadzones. Such a system when compensated on the basis of magnitude…
Design of Controllers for Linearly Varying Inputs: The Design of Controllers for Linearly Varying Inputs discussed in the foregoing sections are for the step input. The performance has been found…
Controller Transfer Function: While a Controller Transfer Function is designed to improve the behavior of a given control system in practice it is very difficult to realize such a controller…
Magnitude Optimum: The design of a controller based on the principle Magnitude Optimum that it allows all the freÂquencies to pass through in a similar way for a simple system is…
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…
Nyquist Criterion: Nyquist Criterion - This stability criterion enables one to establish the stability of a system using a graphical procedure in the frequency domain. Here also there is no…
