| Three axixs simulation table,which is used to simulate the pose and movement of the aerocraft in the air, is one of the most important equipments in Hardware-In- The-Loop Simulation System. The performance of the table is directly related to the productions'capability and precision. So the table with high performance is of great social and economical benefit to the development of aviation industry and construction of national defense.The paper mainly research on the application of the new simulation table in Hardware-In-The-Loop Simulation System. It designs the test software about the dynamic function of the table, and analyses its influence to the results of simulation. It also research on the application of dynamic neural networks in table system.At first, the paper realizes the communication of ethernet network and serial port between the simulation computer and the table control computer. The model-structure programs designed by VC++ language implement communication by using the usual MFC without any limitation of operation systems. It can insert into different simulation programs conveniently, and complement the Hardware-In -The-Loop Simulation experiment on different objects.Secondly, the paper develops a kind of software which is used to test the table's dynamical capability based on the serial port communication. It divides into two parts- the single frequency testing and frequency characteristic testing. The software with friendly users'interface has the function of data storage, and offers the data for the control of neural networks.Lastly, an application of dynamic neural networks in table system is investigated. Based on the choosing of suitable neural networks for the table system, the design process of the neural network feed-forward controller is described in detail .Then, the table is nonlinearly compensated through the method of neural network feed-forward control and simulation is applied to confirm the feasibility of the controller. |
