The widely studied class of minimum phase observable nonlinear systems with output dependent nonlinearities is considered. The problem of tracking any smooth bounded output reference signal is addressed, when the system is perturbed by additive disturbances generated by an unknown stable linear exosystem whose order is known. An output feedback solution is presented which achieves asymptotic tracking...
The proposed adaptive scheme achieves regulation without restricting the nonlinearities by any growth conditions. Motivated by many systems of practical importance, such as most types of electric motors, the dependence on the unknown parameters is restricted by an extended matching condition.
The problem of controlling robots with flexible joints is considered. After recalling the exact nonlinear model it is shown that the model is singularly perturbed if joints are nearly stiff. Singular perturbation techniques are used to add a stabilizing control signal to well established control laws obtained under the assumption of stiff joints.
