气动力模拟器的实时控制分析与软件设计

飞行器实弹、实机测试前必须先进行地面半实物仿真,而空气动力负载模拟器是半实物仿真系统里的必备设备,主要用来模拟飞行器舵面受到的气动力负载,进而检验控制系统在载荷影响下的控制性能。飞行器一般具有很强的机动性,对应的气动力载荷谱幅值范围大,变化极快,所以气动力模拟器的控制实时性能要求极高,控制周期要快至微秒的水平,对软件设计提出了很高的要求。模拟器系统的测控通道很多,工况需求多样,所以软件架构复杂,需要针对模拟器的工况进行详细设计。本文分析了一个典型的气动力模拟器的控制需求,搭建了软件结构,设计了一个通用的控制软件。

Application of Support Vector Machine in Nondestructive Ultrasound Testing

The aerodynamic load simulator is the essential equipment in the hardware-in-the-loop simulation system. It is mainly used to simulate the aerodynamic load on the rudder surface of the aircraft, and then to test the control performance of the control system under the influence of the load. Aircraft generally has strong maneuverability and the corresponding aerodynamic load spectrum has a wide range of amplitudes and changes very quickly. So, the control performance of aerodynamic simulator is required to be very high. The real-time requirements generally reach microsecond level, which puts forward high requirements for software design. There are many measurement and control channels in the simulator system, and the working conditions are various. So the software structure is complex, and it needs to be designed in detail for the working conditions of the simulator. This paper analyses the control requirements of a typical aerodynamic simulator, builds the software structure and designs a general control software.
