摘要:

并发学习是一种最近发展的自适应更新方案,可用于在不需要持续激励的情况下保证参数收敛。然而,该技术需要知道状态导数,这些通常不能直接测量,因此必须进行估计。本文提出了一种新的积分并发学习方法,该方法消除了对状态导数估计的需求,同时保持参数收敛特性。蒙特卡洛仿真展示了其相比传统导数形式在噪声鲁棒性上的改进。

英文摘要:

Concurrent learning is a recently developed adaptive update scheme that can be used to guarantee parameter convergence without requiring persistent excitation. However, this technique requires knowledge of state derivatives, which are usually not directly sensed and therefore must be estimated. A novel integral concurrent learning method is developed in this paper that removes the need to estimate state derivatives while maintaining parameter convergence properties. A Monte Carlo simulation illustrates improved robustness to noise compared to the traditional derivative formulation.
