Optimization of control systems by criterion of highest ensured accuracy
Singularities of problem definition. Similar to the problem of Wiener filter synthesis, which minimizes a total error dispersion at known spectral densities of reference action and interference, it is possible to apply the system synthesis problem, in which the upper-bound estimate of total error dispersion is minimal at known generalized or power moments of reference action and interference spectral densities. The system optimization by minimum upper-bound estimate criterion of total maximal error is also possible, if the available a priori information allows for the calculation of such an estimate for any system admissible variant. In the both cases it is possible to speak about an optimal synthesis of control systems by criterion of the highest accuracy or about minimax robust system synthesis .
