Abstract


People a sense of the system is an important part of the aircraft control system , the main factors affecting aircraft performance . How to improve the performance of the human sense of the system , thereby improving the quality of the operation of the aircraft , the flight control has become a major research direction . Based on the active control technology of the active stick closely related with the flight parameters and operating better quality , is one of the hot people somatosensory system . This paper focuses on active stick developed to carry out a systematic study of the system . Firstly, general studies an active stick system solutions , and the function of the system is perfect, engineering , improve system reliability and system operability improvement study . In the current fly-by-wire system , commonly used a passive steering column system . In order to overcome the passive steering column system and flight parameters detachment shortcomings and ensure the flight safety of the aircraft , the structure of the \In order to achieve the engineering application of the system as soon as possible , this article on how to reduce the system volume to expand the specific research . In the analysis and discussion of common transmission scheme based on gear mechanical transmission of structure - based three-dimensional modeling of the structure ; and use of the UG NX3.0 software to verify the feasibility of the mechanical structure of the model analysis . On the basis of the analysis of the system mechanical structure feasibility study based on the control of the torque motor shaft angle detection . In order to maximize the elimination of the interference of the noise signal , the signal acquisition and processing of in-depth analysis , from software and hardware design , in order to ensure the accuracy of the system control . Combined with two algorithms , fuzzy control and PID control and fuzzy PID composite controller design to guarantee the real-time system control . Through the study of the mechanical structure of the system , three-dimensional model , hardware and software control , the final processing , assembling mechanical structure entities active stick system , system control PCB board design , which laid the foundation for the further development of the prototype .
