The objective of this thesis was to develop circuitry which could augment existing controls on hydraulic servo- systems during start-up and shaft breakage anomalies. A mathematical model was developed in terms of the Laplace transformation. The model evaluation as a type zero, type one and type two system indicated excessive difficulties would exist should normal negative feedback loops be used. Consequently, the two situations were treated as system discontinuities and a circuit using readily available components was developed for each situation. The two circuits are adjustable and should work with any hydraulic servo-system comparable to the one used for this paper. A brief examination of Appendix B by the reader should be sufficient to determine if the system analyzed is similar to those of interest to the reader.
