The application of multivariable control theory to a gas turbine powered ship propulsion unit is described. This propulsion system, which has two independent inputs viz fueling rate and propeller pitch angle, was simulated by a non-linear mathematical model from which locally-linearized transfer function models were extracted at various operating points. The system dynamics vary considerably with operating condition and this resulted in an adaptive controller to cope with the full power range of the vessel. The results show that it is possible to design an adaptive multivariable control system which is satisfactory for both large, extremely non-linear, excursions of operating point and also small step changes. The resulting controller is intrinsically closed loop and may be implemented more simply than the present one. Order from BSRA as No. 54, 909.
