APPLICATION OF INPUT-STATE OF THE SYSTEM TRANSFORMATION FOR LINEARIZATION OF SELECTED ELECTRICAL CIRCUITS

Andrzej Zawadzki – Sebastian Różowicz

   The paper presents a transformation of nonlinear electric circuit into linear one through changing coordinates (local diffeomorphism) with the use of closed feedback loop. The necessary conditions that must be fulfilled by nonlinear system to enable carrying out linearizing procedures are presented. Numerical solutions of state equations for the nonlinear system and equivalent linearized system are included.

Keywords: nonlinear electrical circuits, linearization, feedback linearization, local diffeomorphism, Lie algebras, differential geometric approach
