Abstract :
The solution of a new 3½ degree-of-freedom H∞ /H2 stochastic optimal control problem is discussed which may be either H2 or H∞ optimal. The system includes a 2½ degree-of-freedom tracking controller and a feedforward control action. The feedback controller must be robust and is therefore normally designed to minimize an H∞ criterion. However, the solution obtained is sufficiently general that the feedback, tracking or feedforward control functions can be chosen to minimize either an H2 or a H∞ criterion
