Research On Side Stick Manipulation Based On Adaptive Technology

The passive sidebar unit has many advantages over the traditional center steering column.The electric loading mode is the basic way to realize the sidebar driving device.The external input in the system includes the displacement and torque system.The driver manipulates the side rods and the side rods to shift,and inputs the torque system to obtain the torque feedback of the torque system.Therefore,the driver can obtain the force feedback on the steering column.Perceive the effects of manual sidestick handling.First of all,this paper introduces the development history of the academic field related to the side-bar manipulation using adaptive technology.Through the development of domestic and foreign development,it summarizes the current academic gaps and deficiencies.It also introduces the characteristics of passive sidebar manipulation and introduces the research methods used in this paper,paving the way for the following chapters.Secondly,the hardware composition of the sidebar control system based on adaptive technology is introduced.The design and selection of the hardware platform are introduced in detail,which lays a foundation for the later mathematical modeling.In addition,we explored the research basis of the sidebar control system,and analyzed the hydraulic loading mode and the electric loading mode.After comparing the two loading modes,the servo electric loading method is small in size,easy to maintain,and easy to diagnose.Therefore,this paper chooses the servo electric loading system as the research basis of the sidebar control system.Again,taking the horizontal channel as an example,mathematical modeling is established.The mathematical model includes two parts: the position system and the loading system.Analysis of the system control strategy,for the servo electric loading method,it is necessary to consider how to suppress the excess torque,we can reduce the impact of the excess torque on the system from both software and hardware.The system adopts a control strategy combining closed loop PID control with current loop correction and excess torque feedforward compensation control.Finally,using the design idea of feedback control,at the same time,the actual system is tested and simulated.In order to better compare the actual and simulated working conditions,we take the same input and try to ensure the consistency of the test and simulation.The working curve is compared with the actual working curve,and the response conclusion is obtained to verify the performance of the operating system.
