A Abstract: The problem of controlling complex, nonlinear structural and mechanical systems, such as robotic arms or satellites flying in tight formation, to move exactly along predefined trajectories is of great industrial and practical importance. This paper provides a new and simple, yet powerful and exact, solution to this long-standing problem. It draws its inspiration from the way Nature seems to control complex mechanical systems when their motions are constrained to follow certain trajectories. The results provided appear to be the simplest and perhaps most comprehensive available to date on controlling the motion of complex nonlinear systems along predefined trajectories (...).
