WebDec 30, 2013 · Regarding the MATLAB step response you plotted: your system is marginally stable. This means roughly/intuitively that in the time domain the system output changes no faster than the input (time, for a step response), except for a constant gain (1/2 in your case). However, it does not approximate a final constant value either, which an ...

WebUnstable system has closed loop transfer function with atleast one pole on the right half of s-plane and/or pole of multiplicity greater than 1 on the imaginary axis giving rise to response of form tn cos(!t+ ˚) Marginally Stable System A marginally system has closed loop transfer function with poles only on the imaginary axis with multiplicity 1. WebOct 25, 2015 · But when we use poles p = [ − 1000 − 2000] we find that there is only marginal stability with some steady-state error (although the bandwidth of the steady-state error is small). This is happening because the closed-loop system frequency is so high that there is numerical instability in the simulation caused by the solver's choice of time-step.
