Load torque estimation and passivity-based control of a boost-converter/DC-motor combination / Jesus Linares-Flores in IEEE Transactions on control systems technology, Vol. 18 N° 6 (Novembre 2010)

For the adaptation, the load torque perturbations are assumed piecewise constant and are, nonasymptotically, online estimated using the available noisy measurements of the state variables. The controller is a linear controller based on the exact tracking error dynamics passive output feedback (ETEDPOF) controller design methodology including suitable adaptive feed-forward precompensation depending explicitly on the precisely estimated torque. The performance of the adaptation, which is achieved by means of the algebraic online-estimation of the current unknown load torque, is successfully validated in an experimental laboratory setup.
