摘 要:针对具有模型不确定性、随机干扰和输出受限的柔性关节机械臂系统,本文设计了一 种新的预设性能的自适应控制策略。首先构造了一种能同时适用于有约束和无约束两种情 况的指数衰减时变正切型障碍 Lyapunov 函数,该函数能够克服传统正切型障碍 Lyapunov 函 数不能同时兼顾瞬态和稳态性能的缺陷。在此基础上,利用多维泰勒网络(multi-dimensional Taylor network, MTN)逼近未知函数,结合反步法,为系统设计带有输出约束特性的反馈控 制律。最后,利用 Lyapunov 稳定性理论,证明所有闭环信号在概率上是半全局最终一致有界 的,并通过一个实际算例验证所提出方案的可行性。

Abstract:For flexible-joint robotic manipulator systems with model uncertainties, stochastic disturbances and output constraints, a new adaptive tracking control strategy with prescribed performance is designed in this paper. Firstly, an exponentially attenuated time-varying tan⁃ gent barrier Lyapunov function is constructed, which can be applied to both constrained and unconstrained situations and overcome the defect that traditional tangent barrier Lyapunov func⁃ tions cannot simultaneously consider both transient and steady-state performance. On this basis, the multi-dimensional Taylor network (MTN) is used to approximate the unknown func⁃ tions, and the backstepping method is used to design a feedback control law with output con⁃ straint characteristics for the systems. Finally, based on Lyapunov stability theory, it is proved that all closed-loop signals can achieve semi-global ultimately uniformly bounded in probabil⁃ ity, and the feasibility of the proposed scheme is verified through practical example.
Key words:adaptive control; stochastic disturbances; multi-dimensional taylor network; pre⁃ scribed performance; flexible-joint manipulator
