| 摘 要： | 燃气发生器采用高压空气加燃料燃烧的方式产生持续气流,为了保证发生器的效率和稳定性,燃气发生器对空气压力调节速度和精度要求很高。系统采用压力和位置串级控制方式,并结合模糊PID控制策略,通过优化控制参数,确保了大范围压力调节的动态响应和控制精度,通过试验验证,调压阀位置调节精度优于0.2%,在1.5MPa~5.8Mpa范围内,压力调节时间小于1秒, 压力控制误差小于0.1MPa。

Research and actualization of air pressure control strategy for gas generator |
| |
| Abstract: | The gas generator generates continuous flow by fuel combustion in air. In order to guarantee the efficiency and stability of gas generator, the requirement of regulating speed and accuracy of air pressure is very high. The system use cascade control of pressure and position, bonding with fuzzy PID control strategy. The regulating speed is good and the control accuracy is very high by parameter optimization. The control accuracy of air pressure regulator valve position is more accurate than 0.2%. Between 1.5MPa to 5.8MPa, the regulating time of air pressure is less than one secondand the control error is less than 0.1 MPa . |
