不确定过驱动系统中执行器幅值和速率饱和的处理:改进的投影算法方法

Seyed Shahabaldin Tohidi, Yildiray Yildiz

摘要:

本文提出了一种投影算法,可用于约束的驱动器信号,在幅度和速率,不确定系统的冗余执行器。研究的闭环控制系统被假定为包含一个自适应控制分配器,以分配总的控制输入执行器。虽然传统的控制分配方法可以处理执行器的速率和幅度的限制,他们不能考虑执行器的不确定性。另一方面,自适应分配器管理不确定性和致动器幅度限制。建议的投影算法使自适应控制分配器处理幅度和速率饱和约束。数学上严格的分析表明,所提出的投影算法的帮助下,自适应控制分配器的性能可以得到保证,在误差界。仿真结果表明,所提出的方法的有效性,在研究环境(ADMIRE)中的气动数据模型被用作过驱动系统。

英文摘要:

This paper proposes a projection algorithm which can be employed to bound actuator signals, in terms of both magnitude and rate, for uncertain systems with redundant actuators. The investigated closed loop control system is assumed to contain an adaptive control allocator to distribute the total control input among actuators. Although conventional control allocation methods can handle actuator rate and magnitude constraints, they cannot consider actuator uncertainty. On the other hand, adaptive allocators manage uncertainty and actuator magnitude limits. The proposed projection algorithm enables adaptive control allocators to handle both magnitude and rate saturation constraints. A mathematically rigorous analysis is provided to show that with the help of the proposed projection algorithm, the performance of the adaptive control allocator can be guaranteed, in terms of error bounds. Simulation results are presented, where the Aero-Data Model In Research Environment (ADMIRE) is used as an over-actuated system, to demonstrate the effectiveness of the proposed method.
