Empty state-space model,空的状态空间模型，楼主是在用MATLAB建模吧，是不是模型有什么错误。建模首先要保证模型正确，其次对应的m文件本身也要正确，最后两者还要完美融合在一起，建立的模型才能正确运行。这个过程很容易出现问题，并且不容易寻找，比调试一个单纯的m文件程序更复杂，楼主还是耐住性子仔细...
从原理上说，State-Space模块的Initial conditions应该设置成列向量（因为状态向量x是列向量），但从实际情况看，其实是可以随便设置的，行向量或列向量都可以，甚至设置成矩阵也可以（前提是元素个数能对的上）。猜测很可能是其内部对输入数据做了强制转换成列向量的处理，即使用的是x0(:)。
回复:matlab7.0运行出现Empty state-space model. 收藏 回复 sunwei92 1L喂熊 1 有人知道没啊 sunwei92 1L喂熊 1 还有人出现过这种问题没? 天涯浪子Z 1L喂熊 1 多谢多谢,我也刚刚碰到这问题。搞了半天,不及百度一下,还是人多力量大啊!!!再次谢谢LZ及LS的各位!!! 楚国云 1L喂熊 1 改了还是...
SYS=ss(A,B,C,D)(ss:state space model)用来求出lsim函数所需的系统参数“SYS”.lsim(SYS,U,T)此函数画出LTl系统SYS对由U和T描述的输人信号的时间响应(timerespouse).时间向量T由等距的时间采样点组成,U是一个矩阵,它的列数为输入的数目,它的第i行是输人在T(i)时刻的输人值.例如,t=0:0.01:...
