1. A controller for a generator comprising:
a model reference module configured to receive a setpoint value for each of a plurality of power states, and create a reference-time response within each of the power states;
a difference module configured to compute, for each of the plurality of power states, an error value based upon a difference between the reference-time response and a delivered-power value;
a setpoint-shaping controller configured to, for each of the plurality of power states:
produce a controller output value based upon the error value;
produce an internal power setpoint by adding the controller output value and the setpoint value; and
control a power amplifier using the internal power setpoint.
