Design of Embedded Measurement and Control System for Aircraft Maintenance Simulator Based on Genetic Algorithm

With the development of simulation technology, simulation training has been widely used. Helicopter simulation training has become an important part of helicopter training, and its position is becoming more and more important. In the hardware measurement and control part of simulation training, different ways are adopted, which makes it difficult to maintain the simulator. It is difficult for the maintenance staff of simulator users to have a considerable professional level to maintain the simulator. To some extent, it is difficult to repair the simulator failure in time. For the friction and gear clearance of the servo system, as well as the nonlinear, strong coupling and other nonlinear and uncertain factors of two-phase asynchronous motor, corresponding mathematical models are established. Aiming at the requirements of high precision, fast response and high stability of the instrument system, a fuzzy PID controller based on genetic algorithm (GA) optimization is designed. The measurement and control system is a distributed embedded system, which has the ability to work independently with a single card. Compared with the current PCI, VXI, PC104 and other bus products, it has many measurement and control channels, strong modularity and other advantages, providing a good platform for the simulator hardware measurement and control. The design scheme and functions of the measurement and control card are described.
