\dotx(t) = f(x(t), u(t))

Compensating for unmodeled friction, joint elasticity, and unknown payloads during high-speed trajectory tracking. \dotx(t) = f(x(t)

remains negative, pulling the states back into a bounded residual set around the origin. Core Robust Nonlinear Design Methodologies u(t)) Compensating for unmodeled friction

), perfect asymptotic stability to the origin is often impossible. Eduardo Sontag introduced to quantify robustness. A system is ISS if bounded inputs/disturbances yield bounded states, ensuring the state eventually converges to a neighborhood proportional to the size of the disturbance.
