This paper is concerned with the control of responses from linear and nonlinear systems. In the first part, the recently proposed method of pseudo-fault induction is reviewed. It is shown that a linear system can be made to respond to harmonic excitation as if a nonlinearity of given type and location were present. The method makes use of additional or auxiliary excitation. In the second part of the study, the method is extended to cover the introduction of auxiliary inputs into nonlinear systems. A particular application is described, i.e., the suppression of super-harmonic components from sinusoidally excited nonlinear systems. In both cases, the theory is illustrated using results from numerical simulation.
