用matlab实现以下问题的计算 5
Us=10+10cos(t),Is=5+5cos(2t)该怎么求解?我设了电流之后用solve求解[i,i1,i2,i3,i4,Ut]=solve('i=i1+i3','...
Us=10+10cos(t),Is=5+5cos(2t)
该怎么求解?
我设了电流之后用solve求解
[i,i1,i2,i3,i4,Ut]=solve('i=i1+i3','i3=i4+Is','i2=Is+i1','i=i2+i4','i3*2+Ut-2*i1=0','i4*1-i2*2-Ut=0','i','i1','i2','i3','i4','Ut')
得出的答案是:
i =
Is + (7*z)/4
i1 =
(3*z)/4
i2 =
Is + (3*z)/4
i3 =
Is + z
i4 =
z
Ut =
- 2*Is - z/2
