Background. The research object is the system of mobility of an aircraft simulator. The research subjects are the transfer functions of a dynamic hydraulic stand. The objective is to ensure equality between the transfer functions of a dynamic hydraulic stand, their frequency characteristics and transients under all static and dynamic changes of load unbalance.
Materials and methods. The research of the mobility system of an aircraft simulator was performed by analyzing the control loop using simulation modeling.
Results. The introduction of a computer motion system ensures identity of the transfer functions of hydraulic actuators, equality and aperiodic nature of the transients.
Conclusions. Introducion of velocity, acceleration or error differential correction enhances the accuracy of the set motion parameters’ adjustment of the moving platform, eliminates background traffic, improves the quality of dynamic stand’s control actions and, accordingly, increases the learning opportunities of a simulator in whole.
