| 摘要: |
| 某连续式超声速风洞作为国内首座连续式超声速风洞，马赫数和总压是该风洞最重要的2个流场参数，如何实现总压和马赫数的精确控制和快速稳定调节，是风洞控制系统设计建设过程中需要重点研究的内容。通过分析某风洞流场参数控制原理以及各调节手段的耦合关系，搭建连续式超声速风洞控制系统架构，并给出各关键技术问题的解决措施；通过分段变参数模糊PI控制算法进行总压精确控制，设计了风洞运行控制流程，采用风洞吹风试验进行验证。结果表明总压精度优于0.05%，马赫数精度优于0.000 3，均大幅优于设计指标，证明提出的设计思路是有效的，可为连续式超声速风洞的设计调试提供参考。 |

| Abstract: |
| As the first continuous supersonic wind tunnel in China, Mach number and total pressure are the most important flow field parameters of the wind tunnel, how to precise control and rapid and stable adjustment of total pressure and Mach number is the key in the design and construction of the wind tunnel control system. By analyzing the principle of parameter control of the wind tunnel flow field and the coupling relationship of each adjustment methods, the construction of continuous supersonic wind tunnel control system is constructed, and the solution measure of each key technical problem is given. The total pressure is precisely controlled by the segmented variable parameter fuzzy PI control algorithm, and then the wind tunnel operation control process design is carried out. Finally the wind tunnel blowing test is verified. The result shows that the accuracy of total pressure accuracy is better than 0.05%, the Mach number accuracy is better than 0.000 3, all the flow field parameter is greatly better than the design index, which proves that the design idea proposed in this paper is effective and can provide reference for the design and debugging of continuous supersonic wind tunnels. |
