5.6 Conclusions

This chapter discussed the problem of the disturbance tolerance and rejection for linear systems with different saturation nonlinearities and exogenous disturbances. Disturbances bounded in energy and bounded in magnitude were considered. We established conditions for the bounded state stability of these systems with saturation nonlinearities and exogenous disturbances, and formulated optimization problems for establishing the largest estimates of the disturbance tolerance level and the smallest estimates of the disturbance rejection level. In particular, the restricted gain and the norm of the output were employed to characterize the disturbance rejection capabilities of linear systems with saturation nonlinearities and disturbances.
