The paper analyzes the hysteresis phenomenon of positioning systems with flexible elements for transmitting motion of which piezoelectric actuators are used. The article investigates the influence of hysteresis on the accuracy of positioning systems. A special test bench for conducting research and stand-up methodology for carrying out experimental researches have been used. The test bench includes a computer piezo controller, an inductive displacement sensor and a dynamic data collector used for gathering data and transmitting it to the software package. Mathematical modelling of hysteresis using Matlab/Simulink software package has been done. The performed research has shown that the hysteresis model of maximum dispersion error compared to experimental results makes less than 5%. Thus, it can be stated that the selected method for hysteresis modelling is suitable for precision positioning systems having deformable elements and controlled employing piezoelectric actuators to model hysteresis.
