There are a few different ways to analyze and design nonunity feedback systems for steadystate errors One common method is to use the rootlocus method This method involves finding the roots of the characteristic equation of the system The roots of the characteristic equation determine the stability of the system If the roots are all real and negative the system is stable If the roots are complex the system is unstable Another common method is to use the Nyquist stability criterion This criterion involves plotting the Nyquist diagram of the system The Nyquist diagram is a plot of the transfer function of the system The Nyquist criterion can be used to determine the stability of the system If the Nyquist plot encircles the point 10j the system is unstable Once the stability of the system has been determined the next step is to design the system for steadystate error ...
