转台控制器实时性能的半物理仿真方法

Hardware-in-the-Loop Simulation of Flight Motion Simulator Controller's Real Time Performance

针对转台控制器实时性能难以进行理论估算的问题,运用虚拟转台概念,利用MATLAB中RTW工具包支持的xPC目标构建了转台控制器的半实物仿真系统,在PC机上实现了转台控制器实时性能的半实物仿真.实验结果表明,基于xPC的转台控制器实时性能的半实物仿真方法可以方便地给出控制器的实时性能指标,同时也为基于PC的转台控制器软、硬件快速开发提供途径.

To overcome the difficulty in calculating flight motion simulator （FMS） controller＇s real time index, this paper referred to the concept of virtual flight motion simulator （VFMS）, used xPC target sup ported by MATLAB＇s RTW tools, and built a hardware-in the-loop simulation system for FMS controller＇s real time performance research. The experiment result shows that FMS controller＇s real time index can be obtained easily by hardware-in-the-loop （HIL） simulation and that the simulation platform also provides a way for quick development of FMS＇s controller based on PC.
