Abstract :
A general mixed H2/H∞ optimal control problem is considered. The system consists of a plant and stable weights on the H2 and H∞ transfer functions, and is linear time-invariant. The controller order can be reduced to that of the plant augmented with the H2 weights only. A solution allowing a feedforward term in the H∞ problem and a singular H∞ constraint is developed. An F-16 longitudinal controller is designed to demonstrate the new method.
