LEW-12556 ISPN 19887-662 CONTROL SYSTEM DESIGN USING FREQUENCY DOMAIN MODELS AND PARAMETER OPTIMIZATION, WITH APPLICATION TO SUPERSONIC INLET CONTROLS This program performs an optimization of parameters in a feedback controller transfer function. A frequency domain, quadratic performance index of system error and control effort is minimized by a conjugate gradient search. The controller parameters are handled in a linear...
