  • Abstract
    A Rolls-Royce electrical pump running on active magnetic bearings (AMBs) is described. This rig is controlled by a digital signal processor connected by a custom interface to MATLAB/Simulink hosted by a PC. The PC is able to alter the controller parameters running on the DSP in real time and log sensor data. This interface is used to define an online controller optimisation problem in MATLAB with H and H2 measures of tracking as design objectives. A multiobjective genetic algorithm is used to drive the optimisation for the AMB system. The performance of an optimised controller is compared to that of a manually tuned controller and significant improvements in robustness are observed
