Analysis of Friction Effect on Dynamic Characteristics of Artificial Feel System

Abstract:

A complete mathematical model of artificial feel system of a vehicle fly by wire flight control system was established after analyzing the heading mechanical structure of it. Modeling it by means of centralizing the distributed system parameters and establishing it to dynamic model, the nonlinear factors such as clearance and friction in the system were simplified reasonably. To establish a corresponding mathematical model, the dynamic model was established by means of dynamic equivalent model method resulting in a multi-freedom model. The mathematical model was simulated in Matlab/Simulink by modular way, and results were consistent to trial data. Friction as an important nonlinear factor have impact on system performance, analysis of its effect on dynamic characteristics of human feel system were in the condition of inputting different forms and amplitude signal . This provided guidance for designing system.
