In the industrial indoor transport various devices are used. Recently, the means of transport which use air cushions are more and more popular. Air cushions are particularly useful for transporting heavy loads and devices over the hardened, smooth floor. The air cushions can be directly put under the load. Then, the load is raised of the small height and displaced. The friction force between air cushion and the floor is very small. Therefore, the load can be moved by the operator. The other case of using air cushions in industrial transport is mobile platform with suitable number of air cushions instead of wheels. One of the most important problems in this case is adjustment of the transportation force in individual air cushion. An automatic control system of the transportation force has been proposed in this work. A mobile platform with four air cushions was considered. The pressure in each air cushion was regulated separately in the feedback loop. Two types of control algorithms have been investigated: the standard PID controller as well as the fuzzy logic controller. The investigations contained two cases of platform load. In the first case the load was distributed uniformly on the platform. In the second case load of two air pads was decreased and load of two other was increased. Construction of the platform, mathematical models of the controllers and results of investigations have been presented in the paper.
