An optimal averaging level control problem is defined and solved for a surge tank system. Two averaging level controllers, the ramp controller and the optimal predictive controller are developed utilizing the optimal control policy. These controllers are compared with previously reported averaging level controllers for step and sinusoidal disturbances in inlet flow rate. The OPC results in improved disturbance filtering characteristics for most of the disturbances considered and is very simple to implement.
