PDF-Nyquist for open-loop unstable systems !!Relative stability (gain marg

is equal to the number of openloop poles in the righthalf plane The closedloop system which is openloop stable no openloop poles in RHP is stable if and only if there are no encirclements of. It is known as Nyquist stability criterion It is based on the complex analysis result known as Cauchys principle of ar gument Note that the system transfer function is complex function By applying Cauchys principle of ar gument to the openloop syste Mapping If we take a complex number on the splane and substitute into a function an other complex number results eg substitut ing 4 3 into 2 1 yields 16 30 Contour Consider a collection of points called a contour A Contour A can be mapped Nyquist olar plots olar plot of the frequency resp onse pro duces curv with frequency as parameter relating the oin ts on the olar plot to the appropriate oin ts on the Bo de plots see Fig 1 The Nyquist plot con tains the same information as the Bo When in Loop Bypass mode the SendReturn effects loop is bypassed when the pedal is off In Loop On mode the SendReturn effects loop is active while the pedal is off This can be accessed by removing the back plate of the pedal Up Loop On factory sett (For Voltage Feedback Op Amps).

In practice, the performance of a control system is more realistically measured by its time-domain characteristics.. The reason is that the performance of most control systems is judged based on the time due to certain test signals. . A true “multipurpose tool” - often under utilised and under valued..
