摘要
为了避免执行机构出现饱和而影响系统的稳定性,针对具有双执行机构的碟形飞行器,设计了具有参考输入校正的变结构控制律。参考输入信号根据执行机构的虚拟饱和信号而自适应地进行调整,以保证系统在跟踪过程中的稳定性。控制器设计考虑了各执行机构动态和相互之间的协调配合。仿真结果表明了该方法的正确性和有效性。
In order to avoid the actuator saturation and ensure the stability of the system, a reference trajectory modification control framework is developed to the saucer-shaped aircraft with two actuators. The proposed design methodology has the ability to protect the control law from actuator saturation. The reference trajectory is adaptively modified according to the virtual saturation signals. The actuators dynamics and the cooperation are considered during the design procedure. Simulation results show that the proposed method is correct and effective.
