In this paper, we propose an operational space control formulation for a planar N-link underactuated manipulator (PAN–1)1 with a passive first joint subject to actuator constraints (N ⩾ 3), covering both stabilization and tracking tasks. Such underactuated manipulators have an inherent first-order nonholonomic constraint, allowing us to project their dynamics to a space consistent with the nonholo...
