Given a forced-vibration system descrided by
‥
x1+2x1-x2=asinΩt
‥ (1)
x2+2x2-x1=bsinΩt
(a) If we assign a=0 b=1 and Ω=2 in equations (1),
and the initial conditions are x1(0)=x2(0)=0 and
‧ ‧
x1(0)=x2(0)=0,find the solution of equations(1).
(b)
If the forcing frequency Ω is assigned as Ω=3^0.5
what is the relation between a and b in order that
the solutions of equation (1) with zero initial
conditions are bounded for all time?
這題搞不懂B小題再問什麼... 感謝幫忙解惑的高手
