Abstract

A H ∞ filter is proposed to suppress the adverse effects generated by the measurement noise in the pitch control system of an autonomous underwater vehicle. A kinetic model of AUV´s pitch motion in vertical plane is established by linearizing the nonlinear model at a specified operating point. Based on LMI Lab, it is possible to design a global optimal H_∞ filter for an accurate estimation of the contaminated states which are very important inputs to the feedback controller. It is reported that this filter is effective to eliminate the negative effects caused by measurement noise. And the accurate estimation to the system states means a lot for systems lacking disparate measurement.
