Abstract
A new single range controller design approach for use with nonlinear liquid propellant engines (LPE) is developed. The approach is based on a describing function model of the nonlinear LPE coupled with the application of the Hâ control theory. The approach is applicable to nonlinear LPEs of a general nature without any restrictions on nonlinearity type, number of nonlinear terms, nonlinearity arrangement, or system order. The approach is applied to an existing nonlinear LPE, and the results are compared with those obtained with an alternative method that was previously reported in the open literature.
