对于输出连续测量的非线性连续时间系统,我们提供了新的降阶观测器,收敛于有限时间。收敛时间与初始状态无关。对于测量是离散的情况下,我们提供渐近收敛的观察员,其收敛速度是成比例的负对数的采样间隔的大小。我们的观测器是基于Gramian的可观测性。
For nonlinear continuous-time systems with continuous measurements of the output, we provide new reduced order observers that converge in finite time. The convergence time is independent of the initial state. For cases where the measurements are discrete, we provide asymptotically converging observers, whose rate of convergence is proportional to the negative of the logarithm of the size of the sampling interval. Our observers are based on the observability Gramian.
