Magnitude Optimum: The design of a controller based on the principle Magnitude Optimum that it allows all the fre­quencies to pass through in a similar way for a simple system is…

Controller Design Frequency Response: The Controller Design Frequency Response (or root locus) alters or reshapes the frequency response (or root locus) of the original system to the desired one. Thus…

Control System Performance: From the foregoing discussion on control systems it can be seen that the be­haviour of the control systems can be specified, based on several time domain specifications.…

Relative Stability from the Nyquist Plot: Relative Stability from the Nyquist Plot - The considerations discussed above provide information about the absolute stability of the system, i.e., whether the system…

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…

Polar Plot for Frequency Response: One of them is the Polar Plot for Frequency Response representation. The transfer function in the frequency domain is obtained by substituting jω for s…
