Abstract
A generator and a method for controlling the generator are disclosed. The method comprises receiving a power sequence comprising a plurality of power states, creating a dynamic reference-time response within each state, and determining a dynamic average-delivered-power value within each state. An error signal is calculated within each state, and a controller output is produced using the error signal. An internal setpoint is produced based upon the error signal, and a power amplifier is controlled using the internal setpoint to control output power.

(canceled)
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 plurality of 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 produce, for each of the plurality of power states:
- a controller output value based upon the error value;
- and
- produce an internal power setpoint by adding the controller output value and the setpoint value.
A method for controlling a generator, comprising:
- receiving a setpoint value for each of a plurality of power states;
- and within each of the power states:
- creating a reference-time response;
- computing an error value based upon a difference between the reference-time response and a delivered-power value;
- producing a controller output value based upon the error value;
- and
- producing an internal power setpoint by adding the controller output value and the setpoint value.
A controller comprising:
- a field programmable gate array comprising instructions to program the field programmable gate array to produce a delivered-power value based upon measurements of output power;
- and
- a processor and a tangible computer readable storage medium encoded with processor readable instructions to:
- receive a setpoint value for each of a plurality of power states;
- and
- within each of the plurality of power states:
- create a reference-time response;
- compute an error value based upon a difference between the reference-time response and the delivered-power value;
- produce a controller output value based upon the error value;
- and
- produce an internal power setpoint by adding the controller output value and the setpoint value.
