Design and Research of the Control System for Simulator of Fire Control System in Armed Helicopter

A three-axis electric-driven simulator was designed for the simulation of Fire-Control System in armed helicopter. The main technological requirements of simulator were introduced firstly, and then the control scheme of this system was put forward. The control software was also discussed in detail. VxD (Virtual Something Device) technique was adopted in the real-time software of upper computer. For the communication protocol in this system, double buffer mechanism of both upper computer and lower computer was proposed. The results of hardware-in-the-loop simulation indicate that the whole control system achieves high control precision, whose operation is easy and function is perfect. This simulator has completed many key real-time simulation tasks of Fire-Control Systems for many kinds of armed helicopters, which shows the effectiveness of this new-designed control system.
