| 中文摘要 |
| 提出了一种非线性跟踪控制器的设计方法并应用在某型号航空气动伺服系统中.由于该系统的连接孔和伺服阀组成了一个双约束子系统,因此其气缸内腔压力很难控制.设计了一个改进的反馈线性化控制器用来消除双约束造成的奇点,线性矩阵不等式方法用于确保跟踪误差的稳定性,仿真结果表明该控制器具有良好的动态特性及抗干扰能力. |
| 英文摘要 |
| A nonlinear tracking controller was designed and applied to a class of aerial pneumatic servo systems for which the connection port comprises a non-negligible restriction.The pressure in the chamber of this system is difficult to be controlled because of the servo valve and the connection port forms a double restriction.A modified feedback linearization controller was proposed to avoid this singularity caused by the double restriction.The linear matrix inequality (LMI) was then used to ensure the stability of the tracking error.Simulation results show that the proposed controller has a good disturbance rejection and dynamic properties. |
