Final report on development of adaptive control algorithm for active control of total power input

An adaptive realtime algorithm for minimisation of total power input to a receiving structure has been derived, implemented and tested, and this control algorithm has proved to be robust and reliable. Simulation studies ahve clearly demonstrated that the algorithm behaves exactly as should be expected from frequency domain predictions. Experimental trials in the laboratory have supported these observations. Again, the reductions of the measured total power input to the receiving structure were in perfect agreement with the results obtained by analytically minimising the controller cost function. Apart from the good results obtained with this control strategy under ideal circumstances, observations have also been made of the detrimental effects of 'flanking paths' and measurement errors that may be experienced in a practical implementation.
