Abstract
A novel theoretical framework is presented for making a given linear s ystem respond to external excitation as if a nonlinearity or fault was present. The type and apparent location of the nonlinearity or pseudo -fault may be specified arbitrarily. The means of generating the requi red response is to excite the system with additional inputs, thus expl oiting the principle of superposition. The theory is validated using n umerical simulation of various lumped parameter systems.
