Bulletin of the Polish Academy of Sciences. Technical Sciences > 2024 > Vol. 72, nr 4 > art. no. e150111

This paper presents the novel estimation algorithm that generates all signals of an object described by nonlinear ordinary differential equations based only on easy-to-implement measurements. Unmeasured signals are estimated by using an adaptive approach. For this purpose, a filtering equation with a continuously modified gain vector is used. Its value is determined by an incremental method, and the...

The look-up algorithm of monitoring an object described by non-linear ordinary differential equations

Przemysław Hawro, Tadeusz Kwater, Jacek Bartman, Bogdan Kwiatkowski

Bulletin of the Polish Academy of Sciences. Technical Sciences > 2023 > Vol. 71, nr 2 > art. no. e144603

The article proposes an adaptive algorithm that generates all object signals, including those for which measurements are not performed due to the difficulties associated with on-line measurements. The algorithm is modeled on the idea of the Kalman filter using its equation, however, the selection of gains is optimized in a different way, i.e. the constant values depend on the adopted ranges of adaptation...

The algorithm of adaptive determination of amplification of the PD filter estimating object state on the basis of signal measurable on-line

Tadeusz Kwater, Przemysław Hawro, Jacek Bartman, Damian Mazur

Archives of Control Sciences > 2021 > Vol. 31, No. 1 > 129--143

The article presents the algorithm that enables adaptive determination of the amplification coefficient in the filter equation provided by Kalman. The method makes use of an estimation error, which was defined for this purpose, and its derivative to determine the direction of correction changes of the gain vector. This eliminates the necessity to solve Riccati equation, which causes reduction of the...
