Motor Drive Stabilization in its Chaotic Region
Abstrakt
The paper is concerned with the stability analysisand the control of chaos in a permanent magnet dc drive
system. The stability analysis is based on the eigenvalues of
the Jacobian matrix of the Poincare Map Function (PMF).
Using the auxiliary state vector, the Jacobian matrix can be
determined without the derivation of the PMF. A
compensating ramp signal is used to avoid bifurcation. The
slope of the ramp signal is also determined by the auxiliary
state vector. The results are verified by computer
simulations in the time domain.
