....ballast control problem is very complex due to nonlinear, time varying, uncertain hydrodynamics. Inherent lags arising from the integration of ballast water flow rate commands into weight change makes the control difficult to stabilize. There are some designs that used a bang bang control system [2]. The ARPA s Unmanned Undersea Vehicle (UUV) employed a fuzzy logic ballast controller which was claimed to be comparable with the performance that can be obtained from standard control techniques, but does not require traditional linear or nonlinear design methods. Figure 1. Sectional elevation ....
