Abstract

A nonlinear recycle compensator, which is applicable to both single-variable and multivariable nonlinear systems with recycle is derived. As opposed to the already formulated and widely used linear recycle compensator which involves linearizing the recycled state variable about nominal operating values, the nonlinear recycle compensator is derived from the nonlinear equations. Its implementation thus ensures exact compensation for detrimental recycle effects over the full operating window when compared to the linear recycle compensator, as has been borne out in simulations and experimental data emanating from this work.
