Aerospace Instrument-Making Annotation << Back RECURRENT IDENTIFICATION ALGORITHM OF DYNAMIC SYSTEM STATE MATRIX A.A. Filippov, I.A. Ryabogina New approach to dynamic system linear model receiving is considered. This approach is unlike to system linearization in equilibrium points of a phase trajectory. This approach uses the technique of vector field averaging of linear model phase speed on observation interval and allows to estimate dynamic system linear models local approximation along a phase trajectory. Estimation of state matrix Ф˄ the recurrent form of an algorithm convenient for cyclic calculations in real time modeling of dynamic systems is used. Key words: dynamic system, linear model, space-state systems, phase trajectory, system identification. DOI: 10.25791/aviakosmos.08.2019.817 Contacts: - Pp. 28-32.
