[求助]hinfsyn命令怎么用啊?!

我要用hinfsyn命令设计一个H无穷控制器,命令如下:
=hinfsyn(p,1,1,0,10,0.0001,1).主要是控制对象P怎么输入?
p=(a;b1 b2;c1 d11 d12;c2 d21 d22)的形式.
我输入的不对,matlab提醒我不是system matrix.
请问如何正确输入p?下面是我的p:
a=[0,0,0,0,0,0,1,0,0,0,0,0;
0,0,0,0,0,0,0,1,0,0,0,0;
0,0,0,0,0,0,0,0,1,0,0,0;
0,0,0,0,0,0,0,0,0,1,0,0;
0,0,0,0,0,0,0,0,0,0,1,0;
0,0,0,0,0,0,0,0,0,0,0,1;
-17910.47,0,0,0,0,0,-0.80298,0,0,0,0,0;
0,-234623.98,0,0,0,0,0,-2.90628,0,0,0,0;
0,0,-1138702.41,0,0,0,0,0,-6.4026,0,0,0;
0,0,0,-3543306.28,0,0,0,0,0,-11.2942,0,0;
0,0,0,0,0,-8587478.59,0,0,0,0,-17.5826,0;
0,0,0,0,0,-17735131.92,0,0,0,0,0,-25.2679];
b1=;
b2=b1;
c1=;
c2=[-29.92,-227.37,-765.88,-1818.95,-3548.16,-6132.99,0,0,0,0,0,0];
d11=;
d12=;
d21=0.033;
d22=0.033;

sorry!

sorry!


我发的C1太长,C1修改如下:
c1=[1,0,0,0,0,0,0,0,0,0,0,0;
0,1,0,0,0,0,0,0,0,0,0,0;
0,0,1,0,0,0,0,0,0,0,0,0;
0,0,0,1,0,0,0,0,0,0,0,0;
0,0,0,0,1,0,0,0,0,0,0,0;
0,0,0,0,0,1,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0;
0,0,0,0,0,0,0,0,0,0,0,0];

回复：（tianfen）[求助]hinfsyn命令怎么用啊?!

你的输入好像对不上吧

tianfen 发表于 2006-2-27 22:22

可以的,我试过,各部分矩阵都是符合维度的,用p=(a b1 b2;c1 d11 d12;c2 d21 d22)可以得到一个矩阵的.不过就是用hinfsyn时不行啊!

回复：（tianfen）[求助]hinfsyn命令怎么用啊?!

看了一下这个错误是检查你的p矩阵是否是系统矩阵造成的

对于控制理论不太熟悉不知道什么样是系统矩阵

在matlab检查是否是系统矩阵是有minfo这个函数完成的

你可以doc minfo看看

呵呵，先谢谢了。我问过我师兄，他也不会，我先看看帮助吧，估计还是不会。

tianfen 发表于 2006-2-28 15:52

呵呵。我把它改成了：
b=;
c=;
d=;
p=pck(a,b,c,d) 就有结果了，不过不知道这个结果对不对。
