metoda Lapunowa - Opis:
- New semiconductor power switches make considerable increase of operation frequency of converters in traction drives possible. For this reason the values of the capacitance and inductance of the input filter components could be significantly decreased. However, the significant decrease of the parameter values of these components can be unacceptable due to necessity to ensure the stable operation of the drive system. The method of obtaining the Lyapunov function and the conditions of stable drive's operation are presented in this paper. On the basis of the simplified equivalent diagram of the traction system, which is frequently encountered in literature, the analysis of system operation was carried out. The non-linear differential equation describing the system was formulated, the points of balance were calculated and the practical meaning of these points was discussed. After taking into account the equilibrium points and appropriate transformation of the formulas the known in literature Lienard equation was obtained. On the basis of dependences related to Lienard equation the Lyapunov function for the system analysed in the paper was found. Results of the simulations and laboratory tests of stability of the system with pulse-mode converter supplying the traction motor with rated power of 45 kW of the electric mine locomotive Ld 31 are also presented here.
