论文摘要

机电雄性系统对运动控制具有越来越严格的性能要求,导致在进料控制中不能忽略许多因素(例如位置依赖性)的情况。本文的目的是通过将前馈参数建模作为位置的函数来补偿位置依赖性效果。通过组合高斯过程和前馈参数学习技术来开发一个建模和识别前馈参数作为位置连续函数的框架。该框架导致了完全数据驱动的方法,可以轻松地用于工业控制应用程序。该框架经过实验验证,并显示出商业线螺栓的性能显着提高。

Mechatronic systems have increasingly stringent performance requirements for motion control, leading to a situation where many factors, such as position-dependency, cannot be neglected in feedforward control. The aim of this paper is to compensate for position-dependent effects by modeling feedforward parameters as a function of position. A framework to model and identify feedforward parameters as a continuous function of position is developed by combining Gaussian processes and feedforward parameter learning techniques. The framework results in a fully data-driven approach, which can be readily implemented for industrial control applications. The framework is experimentally validated and shows a significant performance increase on a commercial wire bonder.
