摘要：

Response of systems with the second-order sliding-mode (SOSM) control algorithms to an external harmonic excitation is analysed in the frequency domain. The analysis is done via application of the concept of the equivalent gain of a nonlinear function. The equivalent gain is used as a model of propagation of averaged values of signals through nonlinear elements of the system. Two SOSM algorithms: twisting and super-twisting are analysed. The results are presented in the format of the conventional amplitude and phase frequency response. Copyright (c) 2007 John Wiley & Sons, Ltd.
