โœฆ Synopsis

The loading and unloading of offshore supply vessels pose severe problems in adverse weather conditions when the supply vessel may be heaving, pitching and rolling violently. This is currently overcome by relying on the crane operator's skill and weather windows which may be dangerous and costly. A dynamic platform system (DPS) is proposed here to solve the problem of offshore load transfers. A method of control based on the principle of invariance is Used here on an experimental rig to investigate the control problem of disturbance isolation of the DPS. Good results have been obtained.

This paper presents a new model reference robust adaptive controller which does not require a priori knowledge of the norm desired controller parameter vector. The algorithm is designed according to a reduced order plant which is assumed to be of minimum phase and of an arbitrary relative degree. In
