Description
Summary:Fixed order mixed-norm controllers for the F-18 aircraft are designed to minimize the effects of wind and sensor noise while following a normal acceleration command. The basic objective was to develop a controller of low order that provides good wind and noise response while exhibiting robust performance in terms of command-following in the face of changing flight conditions. Controllers were designed using single norm methods as well as mixed H 2 /H ∞ control with single and multiple constraints and mixed H 2 /μ. optimization. Comparisons illustrate the advantages of mixed H 2 /μ optimization with respect to noise response and controller order while guaranteeing robust performance.
