The publication is targeted to practicing engineers and graduate-level students working in guidance, information command and control systems, and CAD/CAM. The methods covered in this book allow the user to design and analyze nonlinear controllers for nonlinear systems with several important and unique characteristics: the ability to specify the closed loop system's frequency response via requirements on the sensitivity (S) and complementary sensitivity (T), the ability to directly minimize an undesirable resonance or peak in the frequency response while simultaneously closing all loops from the input to the output vector in essentially one single design step, and the ability to analyze the stability characteristics for multiple independent and dependent problem variables. The approach uniquely allows the user to achieve stable and robust performance for systems which are both unstable and contain discontinuous nonlinearities using adaptive nonlinear controllers. 410 0$aProgress in astronautics and aeronautics ;$vv. 205. 606 $aRobust control 606 $aNonlinear systems 606 $aAirplanes$xControl systems$xMathematical models 615 0$aRobust control. 615 0$aNonlinear systems. 615 0$aAirplanes$xControl systems$xMathematical models. 676 $a629.1 s 676 $a629.8/312 700 $aColgren$b Richard D$g(Richard Dean)$01867877 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910973871103321 996 $aApplications of robust control to nonlinear systems$94480789 997 $aUNINA
