  The recursive proportional feedback (RPF) algorithm for controlling chaos is
described and applied to control chemical chaos observed during the
electrodissolution of a rotating copper disk in a sodium acetate/acetic acid
buffer. Experimental evidence is presented to indicate why the RPF method was
used and the theoretical robustness of the algorithm is discussed. (This paper

Scientific Press, River Ridge, NJ, 1995)
