桥式吊车系统信息融合状态观测器设计

Information Fusion State Observer of Overhead Crane System

针对桥式吊车控制系统的所有状态不能全部直接获得的问题,设计了基于非线性信息融合估计的状态观测器,将吊车系统转化成统一的非线性信息融合模型,利用系统的输出状态,构建出信息融合状态观测器,估计系统中不能直接获得的状态,随后的仿真表明了观测器对系统状态估计的准确性。

For the problem of not directly ob- taining all the states of overhead crane control sys- tem, a state observer of nonlinear information fu- sion estimation is designed. A crane system is first transformed into a nonlinear information fusion model, and then uses the output states of the sys- tem to construct the information fusion state ob- server so as to estimate states which are unable to be directly obtained from the system. Simulations demonstrate the accuracy of state estimation.
