This chapter presents a new switching logic–based saturated tracking control (SLSTC) strategy for active suspension systems, which deliberately incorporates advantageous nonlinear stiffness and damping characteristics while exploiting beneficial disturbance effects. In contrast to traditional robust control methods, the proposed controller adaptively alters its control structure to either reject or preserve disturbances based on a newly defined disturbance effect indicator. Furthermore, instead of suppressing the system’s inherent nonlinearities, the controller purposefully utilizes them by tracking the introduced bio‑inspired X‑dynamics.
