摘要：
The paper addresses the problem of parameter estimation of elements in complex, interconnected systems. Similarity between causes of biases in the least squares estimates for a simple SISO linear dynamic object, and for a MIMO linear static system with composite structure, was noticed in the paper. For linear complex static system, the instrumental variable estimate was proposed and compared with the least squares approach. The strong consistency of the presented parameter estimate was proved. Also the optimal values of instrumental variables were established, and the method of their suboptimal generation was presented. The conclusions were verified in numerical experiments.
