论文摘要
在这项技术公报中，我们提出了一种基于观察者的新型自适应方案，以处理偏置正弦信号的参数估计问题。与现有的自适应频率估计方案不同，所提出的方案可以实现固定时频估计，其收敛时间与初始错误无关。具有不同初始值的模拟示例显示了理论结果的有效性。
In this technical communique, we propose a novel observer-based adaptive scheme to deal with the parameter estimation problem of biased sinusoidal signals. Different from the existing adaptive frequency estimation scheme, the proposed scheme can achieve fixed-time frequency estimation, whose convergence time is independent of the initial errors. Simulation example with different initial values shows the effectiveness of the theoretical result.
