In this paper,we investigate and analyze the suboptimal adaptive control for finite impulse re-sponse(FIR)systems with binary-valued observations.As the parameters of FIR systems are unknown and the measurable observations can only provide limited information,we propose and analyze a two-segment design method of an adaptive control law.First,we divide the system running time axis into many sections;each of these sections is divided into two segments.During the short segment,we design the system inputs for estimating parameters.Thus,we employ the empirical-measure-based technique for designing the identi-fication algorithm.Second,we introduce a tracking control law to track a given target based on the system parameter estimates obtained in the short segment.We achieve this using the certainty equivalent princi-ple in the long segment.As the length of short segments tends to infinity,we observe that the parameter estimation algorithm is consistent.However,when the length of segments tends to infinity,we find that the adaptive tracking control law is asymptotically suboptimal.Finally,we demonstrate the efficiency of the two-segment design method using the simulation results.

Snoring is caused by the stenosis of the upper respiratory tract,which can lead to the vibration of the palatine uvula.Snoring brings not only harm to the snorer[1]but also sleep deprivation to those around them[2].Furthermore,stud-ies show that loud snor
