Abstract :
The solution of a H2 stochastic feedback/feedforward optimal control problem is discussed where the structure of the controller is assumed to be fixed a priori. The controller may be chosen to be of reduced order, lead/lag, or PID forms, and the optimal causal controller is required to minimize the usual LQG cost-index. The continuous-time system includes a tracking controller and feedforward control action
