Three-dimensional hoist crane system of automatic control experiment

Overhead crane load capacity, flexible Steel crane, in the industrial and transport fields have a wide range of applications . However, the overhead crane is a typical nonlinear , strong 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 indispensable 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 hoist crane . 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。
