so i supposed that the gain K has value 1 and draw the bode plots..and i found that the phase and gain margin are infinite...i have made a subject for lead , lag and lead-lag compensatin through rlocus and bode methods only in case that the compensator is in series with given transfer...

to be more specific ..so i have to design a lead compensator using bode diagrams, for a system with transfer function G(s)=1/(s+2)(s+3) i have the specifications for settling time and maximum overshoot but not for the velocity constant Kv..my problem is that i only have solved such problems...

Hallo..i have a problem..i didn't know where exactly t quote my question...so i have to design a lead compensator using bobe diagrams, for a system with transfer function G(s)=1/(s+2)(s+3) ..my problem is that the phase margin for this tf is infinite and i don't know how to find the phase tha...

hallo...now i have a problem to solve regarding weigthed automata-in semirings(the automata are defined by matrices).. so i have to find the behaviour automaton through the solution of linear system..for simplicity i have constructed the follwing weigthed automaton : in the semiring of natural...

yesssssssssss it is! :-pthank u again...

thank you very much for the instructions , they helped me to solve the exercise :smile:...i have also read sth that I understand intituitively but i cannot prove formally : L is a lattice and A is a subset of L and we denote with VA and ΛA the supremum and the infinum whenever they exist.Then...

i have a question regarding maths,I have an exercise ...let L be a lattice and we know that it is distributive i.e we know tha aΛ(bVc)=(aΛb)V(αΛc) how can we prove that aV(bΛc)=(aVb)Λ(αVc);;;;;; thanks
