The quantum model of quasi-one-dimensional generalized Fibonacci semiconductor superlattice with the mass of charge carriers depending on the position in superlattice is formulated. The Landauer electrical conductance σ_{L} of generalized Fibonacci semiconductor superlattice is studied analytically and numerically. The dynamical maps allowing us to calculate σ_{L} of the studied systems are presented. It is shown that σ_{L} as a function of incident energy E of charge carriers oscillates strongly and exhibits the resonant character. We have verified numerically that σ_{L}(E) reaches its local maximum for energies E corresponding to energy eigenvalues of charges in superlattice.
