摘 要: | 针对一类欠驱动非线性桥式吊车,设计了一种自适应控制器,它不需要对吊车模型进行近似解耦或线性化处理,不需要事先知道桥吊的精确的数学模型的参数信息,在负载质量等参数发生变化的情况下,能够实现对桥吊小车的精确定位与负载摆动的有效抑制,文中同时对该方法的稳定性进行了理论分析.该控制方法具有结构简单,计算量小的特点.数值仿真结果证实了本控制方法的良好效果.

Anti-swing and Positioning Controller for Overhead Cranes Based on Adaptive Method |
| |
Abstract: | In this paper,an adaptive controller is proposed for underactuated overhead cranes.This controller is put forward without approximately decoupling or linearizing the complicated nonlinear model of overhead cranes.The proposed controller can accurately position the trolley as well as suppress the payload swing even in the presence of uncertainties of system parameters.The controller is simple and easy to apply.The stability of the closed-loop system is proved.To demonstrate the effectiveness of the proposed controller,simulation results are given. |
