中文摘要 |
针对桥式吊车这类非线性欠驱动系统, 提出了一种基于耗散理论的自适应控制器. 它能够有效地抑制运输过程中负载的摆动, 并将其快速准确地运送到指定的位置. 相比其他吊车控制系统, 这种控制器无需准确测量台车和负载质量以及吊绳长度, 可以根据系统响应情况来对这些参数进行在线估计, 这将极大地方便控制器在实际吊车系统中的推广应用. 对于闭环系统的稳定性, 文中通过李雅普诺夫理论及拉塞尔不变性原理进行了证明, 仿真结果也证实了这种自适应控制器能够对吊车系统进行良好的控制. |
英文摘要 |
A dissipativity-based adaptive controller is designed for an underactuated overhead crane system. This controller controls the crane system to transport the payload to a desired location with little swing. Being different from conventional crane control laws, the proposed controller does not measure the system parameters such as the mass of trolley and payload, and the length of the rope; instead, the control algorithm estimates those parameters online according to the system responses. The stability of the closed-loop system is proven by Lyapunov techniques and LaSalle’s Invariance Theorem. Simulation results demonstrate that the designed adaptive controller achieves a superior performance for the overhead crane system. |
