“…In addition, some sensors were installed at the middle of platform to acquire motion status to track and monitor the performance evaluation. To the best of our knowledge, the ideas we mention have not been presented in previously published papers [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. As a result, this paper presents some new ideas in terms of kinematics and a motion-cueing algorithm, the servo motion is executed by the programmable controller, and the commands are read and received through the Ether-CAT communication port to achieve synchronous simulation.…”

Aircraft flight simulators have good cost efficiency, high reusability, and high flight safety. All airlines and aircraft manufacturing companies choose it as sophisticated training equipment for ground simulation, effectively reducing pilot training costs, ensuring personnel safety and aircraft wear and tear. The new simulator proposed in this paper combines a digital motion-cueing algorithm, flight software and motion platform to make pilots feel as if they are in the real world. By using EtherCAT technology to drive the motion-cueing platform, it can improve the data transmission speed of the simulator as well as the strong anti-interference ability of communication and the control operation efficiency. Therefore, the simulated flight subjects can perform long-distance and large-angle training. Next, a set of measurement systems was established to provide monitoring items including attitude, velocity and acceleration, which can be displayed on the screen and recorded on the computer in real time and dynamically. Finally, seven training subjects were implemented to demonstrate the feasibility and correctness of the proposed method.

This study analyzes existing approaches to building fault-tolerant onboard systems at the hardware and software levels. The main advantages of constructing an Avionics Integrated Vehicle System (AIVS) based on fiber optic components are considered, particularly for deploying a Unified Intelligent System (UIS) that provides intelligent decision-making in case of abnormal situations. Scenarios for countering various abnormal situations at different levels of aircraft equipment complex (AEC) operation are developed, aiming to enhance the fault tolerance of its systems and, consequently, flight safety as a whole. Algorithms for reconfiguring the AIVS in case of abnormal situations, both during flight and on the ground, are devised. Principles for creating a specialized knowledge base for information support (KBIS) based on operational documentation are proposed. Logical programming methods are employed to simplify the formalization of knowledge stored in the KBIS and to facilitate modification and supplementation of the KBIS with new data. Calculation methodologies for AIVS configuration characteristics based on the KBIS are developed. Dynamic synthesis methods for generating new AIVS configurations are designed to address abnormal situations arising during aircraft operation. State space information formalized using logical programming methods is used to solve the synthesis problem. A complete system graph is constructed considering its redundancy, and a search-synthesis for the most suitable AIVS architecture capable of countering failures is performed.

The paper presents a DSP-based design and control of a three-axis servo motion system that effectively divides control tasks between the master control terminal and four slave drives. The proposed architecture enhances the immediacy of platform positioning and the integration between software and hardware. The paper utilizes a high-accuracy encoder as a reference value for accuracy improvement and integrates firmware via the proposed embedded execution program, thereby reducing the accuracy error of the low-accuracy encoder. The main control core employs a digital signal processor (DSP) for input and output signal reading and writing, digital communication interface processing, and user interface. The slave controller utilizes four digital signal processors to accomplish servo position control in a digital way. The paper employs encoder calibration technology to upgrade the positioning accuracy of the surge axis. Finally, the paper validates the correctness and feasibility of the proposed method through experimental results from a set of adjustable experimental platforms of linear motion stroke and rotary motion stroke. In summary, the paper underscores the integration of hardware and software to attain high-precision and dependable control of the motion system.
