A Synchronization Algorithm for the Control System of a Multichannel Electromechanical Steering Actuator

The article discusses a common method of constructing a multichannel control system for the steering control of aircraft. To increase the reliability of control, a structure of hybrid steering actuators consisting of electromechanical actuators (EMAs) and hydraulic actuators (HAs) was used. The use of different actuators determines the construction of an adaptive algorithm for synchronizing the position of dissimilar actuators to reduce the forces of mutual loading of the control actuator system. A method for synthesizing an adaptive algorithm for synchronizing position and force for two actuator channels is presented taking into account their nonlinear friction and the nonlinear speed characteristics of the hydraulic valve. The comparison of the efficiency of synchronization algorithms was carried out in the MATLAB/Simulink environment.
