A Comparison of Constant and Variable Amplitude Command Shaping Techniques for Vibration Reduction
We investigate the characteristics of constant-amplitude input shapers for robust time-optimal maneuvers of exi-ble structures. Trends in the timing of the shaper impulses are shown as a function of the system damping constant and move distance. The insensitivity to modeling errors, time-optimality, amount of vibration caused during maneuvers, and high frequency excitation of these shapers are ...
متن کاملVibration Reduction Using Multi-Hump Extra-Insensitive Input Shapers
Input shaping is a method for reducing residual vibrations in computer controlled machines. Vibration is eliminated by convolving an input shaper, which is a sequence of impulses, with a desired system command to produce a shaped input. The shaped input then becomes the command to the system. Requiring the vibration reduction to be insensitive to modeling errors and system nonlinearities is cri...
متن کاملUnity-magnitude Input Shapers and Their Relation to Time-optimal Control
Input shaping reduces residual vibrations by convolving a sequence of impulses, an input shaper, with the desired system command. Using negative impulses in the shaper leads to faster maneuvers. Unfortunately, when negative input shapers are used, there is no guarantee that the shaped command will satisfy actuator limitations. A new type of negative input shaper is presented that satisfies actu...
متن کاملDesign and Implementation of Time-optimal Negative Input Shapers
Input shaping is a method for reducing residual vibrations in computer controlled machines. Vibration is eliminated by convolving a sequence of impulses, an input shaper, with a desired system command to produce a shaped input. The shaped input is then used to drive the system. The input shaper has traditionally contained only positively valued impulses. However, when the impulses are allowed t...
متن کاملHybrid Input Shaping and Feedback Control Schemes of a Flexible Robot Manipulator
This paper presents investigations into the development of hybrid control schemes for input tracking and vibration control of a flexible robot manipulator. A constrained planar single-link flexible manipulator is considered and the dynamic model of the system is derived using the assume mode method. To study the effectiveness of the controllers, initially a collocated PD control is developed fo...
متن کاملImplementation of Input Shaping on Flexible Machines with Integer Controllers
This paper presents an input shaping method for building in real time a shaped velocity profile according to an integer algorithm that determines the command reference signal at each interpolation step. This integer implementation has the drawback of slightly reduce shaping robustness. However, experimental results confirm residual vibration reduction when robust shapers are used in the integer...
