This dissertation presents data-driven control and fault detection approaches for nonlinear Euler-Lagrange systems with model uncertainties, unmodelled dynamics, external disturbances, input constraints, and underactuation. Based on time-delayed control and time-delayed estimation, several methods are developed, including a universal residual generator for sensor fault detection, a data-driven optimal control approach for fully actuated systems, an adaptive control method for underactuated systems, and a sliding model predictive control framework. The proposed approaches are supported by theoretical stability analysis and validated through simulations and experiments on robotic and aerial systems.
