| 中文摘要 |
| 机翼的主动颤振抑制技术是现代弹性飞行器设计的重点, 传统的基于输出量最小化设计的线性二次最优调节器(LQRY)由于引入的信息量少, 其抑制颤振的效果并不理想. 本文提出了一种基于输出微分项推导的最优调节器(ORW)设计方法. 与LQRY方法相比, 该方法引入了更多的系统信息, 能够有效抑制无法直接测量的输出微分项的振动, 从而更快地抑制输出的振动. 最后对典型的气动弹性主动控制系统(BACT)模型, 分别采用LQRY和ORW调节器对机翼颤振进行抑制, 仿真结果表明, 新方法能够更加快速有效地抑制机翼的颤振. |
| 英文摘要 |
| The suppression of active flutter on a flapping wing is a major topic in the design of modern flexible airplanes; but the traditional linear quadratic optimal regulator(LQRY) based on the minimization of the weighted output doesn’t work well for this purpose. A new optimal regulator based on the minimization of the output rate weighted minimizing(ORW) is developed. Being different from the LQRY, this regulator makes use of more system information. It minimizes the time-rate of the output, which is not available for a direct measurement, thereby suppressing the flutter more quickly. Simulation is
performed on a Benchmark Active Control Technology(BACT) system by using the ORWregulator and the LQRY regulator respectively. The results show that the ORW regulator provides a better performance. |
