Typical gantry crane nonlinear systems

Overhead crane load capacity, flexible operation, in the industrial and transport fields have a wide range of applications . However, the overhead crane is a typical nonlinear , hoist gantry crane coupling, due to the drive system to achieve efficient control of its security is facing many difficulties , therefore , control of such systems has become a hot topic. Various crane control methods proposed in recent years , such as sliding mode control, adaptive control , although theoretically possible , but taking into account nonlinear interference and coupling phenomena that exist in the actual system , its usefulness remains to be tested. Experimental methods have become characteristic analysis system , controller design, stability verification steel crane technology tools. For these reasons , we designed and developed a three-dimensional overhead crane system is automatically controlled experiment , in order to verify the relevant control strategies implemented to provide a great convenience . The system can not only simulate the actual operation of the real good cable car system , and is very easy to test a variety of control algorithms and adjustments. In order to verify the reliability of the experimental system , the number of species on the overhead crane control method is applied to the experimental system , the experimental results are consistent with the theoretical analysis of the original documents , which illustrate the effectiveness of the system. Introduction bridge crane overhead crane system is a typical nonlinear systems owe drive .
