The article describes the construction of the control system of the test stand for wheelchair testing. The device allows to control drive systems (asynchronous motors) through two independent inverters, read data from torque meters for each axis independently and force sensors to determine the center of gravity located on the wheelchair stand. The system was built based on a PLC controller with input-output modules. Everything works under the control of the real-time operating system. The system enables the synchronous recording of individual data with a constant time determinism. The data was also displayed on a specially prepared visualization. An Ethernet interface was used for communication. In the experimental part, selected measurement results are presented in the form of graphs. These results can be used to verify simulation models, as well as to obtain information about the biomechanics of the movement of people with reduced mobility, who use wheelchairs on a daily basis.
