Combined method of improving the filtration efficiency of the state variables
The article discusses the optimal control problem using the "output" regulator. Construction of optimal controller is based on the construction of "output" knob and filter state variables. Quality control in this case depends on the quality of finding estimates of state variables. Therefore, as a state variable filters are used improved state variable filters, built on the correct formulation of the problem of filtration, which takes into account all factors, including the effect of mismatch of initial conditions of state variables of the object and the filter. Improved filter state variables constructed on the basis of Wiener filter and the accounting impact of the mismatch of the initial conditions of state variables of the object and the filter. To evaluate the effectiveness of the proposed approach using integral quality criteria. The results of experimental studies developed by the regulator, which confirms the high efficiency of the developed controller.
