Control parameter optimization of a pre‐stressed, shallow cylindrical panel relative to a specified quadratic performance measure is investigated. The excessive transient panel vibrations are suppressed by means of a combination of open‐loop and closed‐loop controls. Based on the assumption that the closed‐loop control law is proportional, the optimal open‐loop control is derived in closed form through minimization of the performance measure via a calculus‐of‐variations approach. Subsequently, the optimal feedback control parameter is obtained numerically. Numerical results and simulation are presented and indicate that a feedback control mechanism may be effectively utilized in the presence of an open‐loop control. © 1997 John Wiley & Sons, Ltd.
