| description | The aim of this thesis was to develop a fast and continuous digital sampling controller to study and compare some of the common arrangements of modern digital and analogue controllers. Most of the work was devoted to building the controller and developing a special management programme so as to obtain the required sampling speed. This programme is discussed in detail in this thesis. The use of direct memory addressing multiplication tables gives rise to serious accuracy problems and an analysis is made thereof. The controller was based around the APPLE personal computer which is well known for the flexibility of its peripheral BUS. Utility programmes were written to solve some of the tedious and frequent linear algebraic equations involved in MIMO state space analysis of control. These programmes were used extensively during the testing phase of the controller as applied to a multivariable system which was a coupled electric drive. Finally a brief study was made of the other possibilities of the controller and its algorithms. |
