Algorithms of Sustainable Estimation of Unknown Input Signals in Control Systems

Abstract: The problem of estimating unknown input effects in control systems based on the methods of the theory of optimal dynamic filtering and the principle of expansion of mathematical models is considered. Equations of dynamics and observations of an extended dynamical system are obtained. Algorithms for estimating input signals based on regularization and singular expansion methods are given. The above estimation algorithms provide a certain roughness of the filter parameters to various violations of the conditions… Show more

“…However, on electrodes with a large amount of catalyst, a uniform distribution of the active mass on the surface and the lowest ohmic resistance are achieved. Based on experimental data [12][13], the following rational constructive and technological parameters of the sensitive element were determined: thickness of the gas-permeable base 5.510 -2 сm; pressing pressure 250 kgf/сm 2 ; the concentration of the hydrophobizing agent in the active mass is 5.0%, the amount of catalyst per 1 сm 2 of the electrode surface is 20 mg/сm 2 for freshly prepared electrodes with the specified parameters and the specific surface of the platinum catalyst 16÷18 mg/сm 2 Рt. The actually obtained current density at a carbon monoxide concentration of 36  10 -11 mol/сm 3 (1,0 mg/сm 3 ) was 1.5÷1.6 А/сm 2 , which quite satisfies the requirements for the value of the conversion coefficient when measuring the CO concentration in the range of 1÷400 mg/m3.…”

“…Previously, the technology could not focus on mobile systems, since the data transmission in wireless technology meant a lot of energy and required specialized communication equipment. The situation changed with the low power technologies advent, which are characterized by low energy consumption, small dimensions, high productivity and low purchase price [13,14].…”
