Abstract

A problem of performance enhancement for multiple frequencies estimation is\nstudied. First, we consider a basic gradient-based estimation approach with\nglobal exponential convergence. Next, we apply dynamic regressor extension and\nmixing technique to improve transient performance of the basic approach and\nensure non-strict monotonicity of estimation errors. Simulation results\nillustrate benefits of the proposed solution.\n
