我试图让MATLAB创建一个带有初始值的状态空间模型，后来我必须使用系统识别工具箱进行微调。
问题是我正在使用＆＃34; white-box＆＃34;模型，这意味着我的模型中的A矩阵不仅仅是一个数值矩阵，而是由几个其他参数组成。
由于构成矩阵的每个参数都具有物理意义，因此我想单独估计而不仅仅是A矩阵的值。
这有可能吗？看过genss，idss和其他几种工具，但是还没有能够使它们中的任何一种工作。
我正在使用的系统版本如下（C和D矩阵不相关，因为这只是测试真的）：
A = [-H_infil/Ca+Hsa_i^2/(Ca*(Hms_i+Hsa_i))-Hsa_i/Ca-H_win/Ca+Hsa_e^2/(Ca*(Hsa_e+Hms_e))-Hsa_e/Ca-H_vent/Ca Hsa_i*Hms_i/((Hms_i+Hsa_i)*Ca) Hsa_e*Hms_e/((Hsa_e+Hms_e)*Ca);
Hms_i*Hsa_i/((Hms_i+Hsa_i)*Ci) Hms_i^2/((Hms_i+Hsa_i)*Ci)-Hms_i/Ci 0;
Hms_e*Hsa_e/((Hsa_e+Hms_e)*Ce) 0 Hms_e^2/((Hsa_e+Hms_e)*Ce)-Hms_e/Ce-Hem/Ce];
Bc = [Hsa_i*S*wi/(Ca*(Hms_i+Hsa_i))+S*wa/Ca Hsa_i*fi/(Ca*(Hms_i+Hsa_i))+fa/Ca+Hsa_e*fe/(Ca*(Hsa_e+Hms_e)) H_infil/Ca+H_win/Ca H_vent/Ca;
Hms_i*S*wi/((Hms_i+Hsa_i)*Ci) Hms_i*fi/((Hms_i+Hsa_i)*Ci) 0 0;
0 Hms_e*fe/((Hsa_e+Hms_e)*Ce) Hem/Ce 0];
Cc = [0 0 0];
Dc = [0 0 0 0]
我意识到我可能会遇到几个解决方案的问题，但后来我认为系统识别只会选择一个。
有什么想法吗？
提前致谢！
