accident AI= air instrument
si m=w tt va bien 
si m aug alors Yr diminue 
regulateur sens inverse 

K = 100/BP 

quand Ti = 5s et on augmente de 10%
10/5=2t

SNCC = systeme numerique commande controle
LAPLACE:
derivee L[dx(t)/dt] = p*X(p)
primitive L[intx(t)*dt] = X(p)/p
valeur finale lim x(t)=lim p * X(p)
                t->oo   p->0           
linearite L[lamnda*x(t)+micro*y(t)] = lamda*X(p)+micro*Y(p)
retard L[x(t-T)]=X(p)*e**-T*p
