| 摘要: |
| 针对考虑输入幅值与速率受限的高超声速飞行器跟踪性能问题,提出基于受限指令滤波器的预设性能控制方案。为了提高系统瞬态和稳态性能,设计预设性能反演控制器,并通过设计新的性能函数使得跟踪误差超调量更小。引入指令滤波器来处理反演控制器设计中难以求导的问题。针对输入受限问题,构造一种受限指令滤波器来约束系统控制律,保证控制输入满足幅值和速率的限制要求,并进行相应的理论证明。另外,考虑系统参数不确定性与外界干扰,采用线性扩张状态观测器进行观测并补偿。基于Lyapunov稳定理论证明系统的所有跟踪误差最终一致有界。通过仿真验证该方法的有效性。 |

| Abstract: |
| For the tracking performance problem of hypersonic vehicle with actuator constraints of amplitude and rate, a prescribed performance control scheme based on constrained command filter was proposed. In order to improve the transient and steady state performance of the system, a prescribed performance backstepping controller was designed. And a new performance function was designed to reduce the tracking error overshot. A command filter was introduced to solve the problem of difficult derivation in the design of backstepping controller. For the problem of limited input, a constrained command filter was constructed to constrain the control law of the system, which guaranteed that the control input meet the limit requirements of amplitude and rate, and the corresponding theoretical proof was carried out. In addition, the linear extended state observer was used to observe and compensate the system parameter uncertainties and external disturbances. Based on Lyapunov stability theory, it was proved that all tracking errors of the system are ultimately uniformly bounded. The effectiveness of the proposed method was verified by simulation. |
