Part II – TFI and Its Applications

tfi: creates the TFI environment where the following applications are available:
con[vert],gi,gj: converts gi from s to z and saves the result as gj
defa[ctf],gi,gj: defactors gi and saves the result as gj
deft[f],gi: defines gi with the mouse or as Bessel, Butterworth, Padè tf
des[crf],gi: analyzes a nonlinear system with the describing function
dpop[ov],gi: p lots the Popov diagram of gi
fac[tf],gi,gj: factors gi and saves as gj
fre[sp],gi: plots the frequency response of gi
gpm[arg],gi: displays the (generalized) gain and phase margin of gi
inv[tr],gi: displays the inverse Laplace (or z- ) transform of gi
lag[c],gi,gj: designs a lag compensator (with the Bode diagrams)
lea[dc],gi,gj: designs a lead compensator (with the Bode diagrams)
mak[eleg]: creates or cleans a legend in the last figure
nls[im],gi,gj,gk,gw: plots the time response of a nonlinear feedback system
per[ftra],gi,gj,gk,gw: designs a digital perfect tracking compensator
pidc,gi,gj: designs a PID regulator (with the Bode diagrams)
pidd,gi,gj: designs a discrete-time PID regulator (with the Bode diagrams)
pidn[ich],gi,gj: designs a PD, PI or PID regulator (with the Nichols diagram)
regd[ph],gi,gj,gk,gw: designs a regulator by pole assignment with the Diophantine equation
regn[ich],gi,gj: designs a lead or lag compensator (with the Nichols diagram)
regr[ootl],gi,gj: designs a compensator or a regulator with the root locus
rob[par],gi,gj,gk,gw: analyzes robustness versus parameter variations
roo[tl],gi: plots the root locus of gi
rou[th],gi: displays the closed-loop stability intervals of gi
sam[ptime],T: defines the current sampling time for discrete-time systems
sel[ect],gi,gj: interactively selects factors from gi and saves as gj
sta[rtint]: defines some TFI environment settings
tfe[val],gi: evaluates gi at a particular value of s or z
tre[sp],gi: plots the impulse or step response of gi
wpl[ane],gi,gj: converts from z to w -plane or from w to z-plane
zpp[lots],gi,gj,gk,gw: plots the zero-pole maps of some transfer functions.
