Abstract: Traditionally, cam-follower systems are designed by assuming a constant camshaft speed. Nevertheless, all cam-follower systems, especially high-speed systems, exhibit some camshaft speed fluctuation ...

Abstract: This paper describes a new feedforward algorithm for accurate tracking control of nonminimal phase systems. Accurate feedforward calculation involves a prefilter design using the inverse system ...

Abstract: This paper describes the parameterization of robot excitation trajectories for optimal robot identification based on finite Fourier series. The coefficients of the Fourier series are optimized for ...

Abstract: A moving linkage exerts fluctuating forces and moments on its supporting frame. One strategy to suppress the resulting frame vibration is to reduce the exciting forces and moments by adding ...

Abstract: This paper extends previous work concerning convex reformulations of counterweight balancing by developing a general and numerically efficient design framework for counterweight balancing of arbitrarily ...

Abstract: This paper illustrates the power and versatility of the convex programming framework for optimal spline synthesis that was developed in a companion paper (, , , , , and , 2009, “Optimal ...

Abstract: This paper develops a general framework to synthesize optimal polynomial splines for rigid motion systems driven by cams or servomotors. This framework is based on numerical optimization, and ...

Abstract: This paper addresses the selection of the optimal trajectory and transmission ratio for a servo motor driving a purely inertial load. Both aspects are studied with respect to the required motor ...
