| Abstract: | Data acquisition from underwater glider system yields large amounts of
data. This may lead to a long computational time during the identification
process. The raw data may also contain complex system disturbance information
which may require a sophisticated optimization algorithm to achieve desirable
results. In this paper, frequency sampling filters approach is used as a tool
to compress the data and obtain meaningful parameter that describes the
empirical model of the system. The use of finite impulse response model and the
maximum likelihood method will play a role in eliminating the bias and noise
effects of the glider data systems. By performing this procedure, the
compressed, cleaned and unbiased data will be obtained, in which, it can be
further used to develop a model of the glider system, also to analyze and
observe for optimization and controller design purposes. |
