This thesis presents the results of a three year research project carried out by the author from October. 1964 to June. 1967 while a Commonwealth Scholar in this country. The contents of the thesis are divided into three parts. Part I describes the analytical and experimental studies on a second-order bang-bang servo under non-ideal operating conditions. The sensitivity and stability of the bang-bang system have been, investigated. This work was carried out during 1964-65 while a research scholar at the Queen's University of Belfast. Part II of the thesis is entitled "Self-optimisation using Pseudo-Random Binary Sequences". In this part, the performance of the original hill-climbing system which employs discontinuous parameter adjustment and of the modified system using continuous parameter adjustment is described. It is shown that the system with continuous parameter adjustment has a superior performance. A novel analogue running averager has been developed which is simple and inexpensive. Part III describes an investigation into the frequency response of a sample-and-hold element at certain sampling frequencies.
