The uncertainties in this system are assumed to satisfy a certain integral quadratic constraint. For a given initial condition, the minimax optimal controller is constructed by solving a parameter‐dependent Riccati equation of the game type. This controller leads to a closed‐loop uncertain system which is absolutely stable.19enabsolute stabilitydifferential gamesminimax controlRiccati equationsrobust LQR controlrobust performanceuncertain systems199510.1002/rnc.45900502040029292478
