Quasi Analytical State Observer in Real Time Lerneable System

Application of state variables in description of linear and non-linear dynamic systems brings many advantages therefore that description is frequently used in modeling and simulation. For digital simulation using PC such system needs fundamental matrix for chosen sampling interval to be calculated. Such calculation, which uses finite number of input elements from infinite sequence, is therefore biased with computation error. Various ways of computation varies in precision and speed of calculation. If there is no need to realize real-time computation, precision can be improved using convenient type and number of sequences. The modern control of non-linear dynamic systems (positional servomechanisms) requires "real time" fundamental matrix calculation. In such a case the most suitable way is to apply a procedure developed by the author named quasi-analytical calculation of fundamental matrix, described in this paper.
