Weather satellite scan mirror performance often demands high pointing accuracy, rapid reposition times, and low peak power consumption. This work addresses and compares various techniques for optimizing these specific performances when the scan pattern is repetitive. We find that a technique combining open and closed-loop control in a timed sequence can often lead to the lowest pointing error in the shortest time interval while minimizing peak power. The technique applies equally well to applications such as robotics, automated manufacturing or any other electromechanical control system where quick, accurate response is needed while minimizing peak power.
