Description

This classic magnetic levitation control problem is now presented in a new and innovative form. A 25mm diameter, hollow steel sphere is suspended in space with visually appealing results and convenient time constants. Both analogue & digital control solutions are implemented. Convenient sockets on the enclosure panel allow for quick changes of analogue controller gain and compensation components. The equipment is self-contained in analogue mode, with built-in power supply. In the digital mode the system operates within a MATLAB environment which allows the system parameters to be determined and the system to be modelled. Once the digital controller parameters have been determined, the controller can be used to run the hardware and the actual control performance can be seen and analysed.
