ABSTRACT:
A device in accordance with the present invention includes drive circuitry (110) coupled to a plant (120). The drive circuitry (110) generates a first set of command signals to transition the state of the plant (120) from an initial state to an intermediate state at a first discrete time. The drive circuitry (110) generates a second set of command signals to transition the state of the plant (120) from the intermediate state to the final state at a second discrete time. A state estimator (130) is coupled to the plant to detect the state of the plant (120). A method for changing the state of a plant (120) is also provided. The method includes the steps of transitioning the plant (120) from a first state to a selected state at one of a plurality of discrete times, each of the discrete times being separated by at least one discrete time interval, and transitioning the plant (120) from the selected state to a final state at another of the plurality of discrete times.
