In this paper, a comparative dynamic analysis of the portal cranes of type H and X is described. The difference of the considered cranes arises from the difference of their portals. These two types of portals have the same main geometric measurements. They differ only at the medium level in the horizontal plane. The first type of the portal on the middle level has an H-frame, while the second type has an X-frame. In this paper, dynamic parameters of the two portals have been compared. Estimation has been done to find which of the two types of portals has more favourable dynamic stability for overturn.
W artykule przedstawione zostały rezultaty badań prowadzonych na obiekcie rzeczywistym dwudźwigarowej suwnicy pomostowej w celu opracowania inteligentnego systemu sterowania. Zaproponowany algorytm aterowania oraz układ pomiarowo-sterujący został opracowany i zrealizowany w procesie szybkiego prototypowania, a następnie zaimplementowany na sterowniku docelowym, programowalnym sterowniku logicznym PLC.

The paper presents methodology and results of researches conducted on the real device, the two-spare overhead crane to elaborate intelligent control system based on fuzzy controller with Takagi-Sugeno-Kang inference system. Applied programming environment based on Matlab program and hardware's solutions gave possibility to built control system using rapid prototyping method. The proposed control system was eleborated, built and optimized during simulations conducted on mathematical models of the device and experiments conducted on the real device and next the control algorithm was implemented on the final control device, programmable logic controller PLC.
