Abstract

Input shaping is an effective way to optimize the performance of robots, flexible structures, spacecraft, telescopes, and other systems that have vibration, control authority, tracking, and/or pointing constraints. These constraints along with the dynamics and kinematics of the system under consideration can be included in a trajectory optimization/path planning procedure to ensure that the system meets the desired performance. Input shaping is particularly useful when the closed-loop controller cannot be modified or tuned. For example, many pedestal-based robots have closed architecture control systems that restrict access to the servo-loop controls. This chapter begins with the overhead gantry robot and a vibration constraint referred to as swing-free input shaping.
