Simultaneous Estimation in Linear Dynamic Systems with the Indeterminate Structure Disturbances

Theoretical Aspects of Modern Engineering

“…As a result, the pulses of the periodic sequence, fed from the output of the shaper to the inputs 1 of the logic elements AND 1 , AND 2 , can pass to the input 1 of the unit for forming the second time gate, when at the input of 2 elements AND 1 there is a gating pulse. They pass to the input 2 of the forming unit when there is no gating pulse at the input of the inverter [255]. Figure 2.…”

Generalized Structure of the Model-Oriented Difference Signal Former

“…Determination of the technical state of the control object based on the results of measurements of input and output signals in the event of malfunctions, disturbances, unforeseen changes in parameters, unaccounted for nonlinearities, noise and other destabilizing factors. An example of solving such a problem under the influence of destabilizing factors in an indefinite structure can be the work [1]. In work [2], the estimation of faults in the presence of disturbances of an uncertain structure is carried out together with the state of a linear dynamical system.…”
