A control system is proposed for accomplishing this function which is entirely fluidic, from sensing the necessary variables to applying the required correction torques. The design of the system, excluding the output power amplifiers and actuators,is described in detail. The system is implemented in the form of a demonstration model to illustrate the design techniques. The results of experiments carried out on this model are presented and discussed.Thesis
