INVESTIGATIONS ON SOME POLYNOMIAL LIENARD–TYPE SYSTEMS: NUMBER OF LIMIT CYCLES, SIMULATIONS

Vesselin Kyurkchiev, Anton Iliev, Asen Rahnev, Nikolay Kyurkchiev

Abstract


In this paper we consider a new extended Lienard–type planar systemwith the polynomial P2n+1 of the best Hausdorff approximation of the function sgn (x).The number of limit cycles is also studied.The discussions are related to solving some technical problems such as the synthesisof antennas and electrical circuits.
