A Novel Constrained Time Delay Estimator
نویسنده
چکیده
A novel adaptive algorithm that estimates the difference in arrival times of a signal at two separated sensors is derived. The system consists of a transversal FIR filter whose coefficients are expressed in terms of the estimated delay and they are adjusted by using the LMS method. The mean square error performance surface is multimodal and proper initialization is required to ensure global convergence. Convergence analysis is given and simulation results are also included to illustrate the performance of the time delay estimation algorithm.

This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. Parameters of the fuzzy estimator are adapted to minimize the estimat...
