## Document Summary

Figure (cid:893) (cid:888): second order system pole location n the unit step response of g(s) can be derived using standard table of. 134 | p a g e e t n. If the unit step input is used, the process dc gain and time constant can be evaluated directly from the graph, as was illustrated in previous chapters. We will now demonstrate that the damping ratio and the frequency of natural oscillations can be evaluated from the response plot as well. 7. 2 response specifications for the second order underdamped. Peak time is defined as the time the oscillatory response reaches its (cid:373)a(cid:454)i(cid:373)u(cid:373), as show(cid:374) i(cid:374) figu(cid:396)e (cid:1011) 3. let us assume that the process is des(cid:272)(cid:396)i(cid:271)ed (cid:271)(cid:455) the t(cid:396)a(cid:374)sfe(cid:396) fu(cid:374)(cid:272)tio(cid:374) i(cid:374) e(cid:395)uatio(cid:374) (cid:1011) 1.
