CLAIMS

What is claimed is:

1. A method for controlling velocity of an at least partially resonant actuator system, the method comprising:

determining with an actuator controller computing device a sequence of full bridge and half bridge outputs to substantially control an output velocity of an at least one at least partially resonant actuator device;

controlling with the actuator controller computing device a driver system to output a driving signal based on the determined sequence of full bridge and half bridge outputs; and

providing with the driver system the driving signal to the at least one at least partially resonant actuator device.

2. The method as set forth in claim 1 wherein the driver system is a full bridge driver device.

3. The method as set forth in claim 2 wherein the full bridge driver device is configured to perform:

switching between a first and a second switching state for providing the full bridge output; and

replacing one of the first and the second state by a third switching state for providing the half bridge output based upon the determined sequence of full bridge and half bridge outputs.

4. The method as set forth in claim 2 wherein the determining further comprises:

determining a duty cycle value for the full bridge driver device based upon a measurement of the output velocity;

incrementing an accumulator by adding the determined duty cycle value to a value of the accumulator;

outputting a half bridge cycle when the incremented value is less than a predetermined value of the accumulator; and

outputting a full bridge cycle when the incremented value more than the predetermined value of the accumulator,

wherein successively outputting the half bridge cycle and outputting the full bridge cycle forms the determined sequence of full bridge and half bridge outputs.

5. The method as set forth in claim 1 wherein the providing further comprises providing the half bridge output at an end of at least one of a low to high transition point of the full bridge output and at a high to low transition point of the full bridge output.

6. The method as set forth in claim 1 further comprising: controlling the output velocity of the at least one at least partially resonant actuator device in proportion to an amount of power consumed by the at least partially resonant actuator system, wherein the amount of power consumed depends upon the determined sequence of full bridge and half bridge outputs.

7. A computer readable medium having stored thereon instructions for controlling velocity of an at least partially resonant actuator system comprising machine executable code which when executed by at least one processor, causes the processor to perform steps comprising:

determining with an actuator controller computing device a sequence of full bridge and half bridge outputs to substantially control an output velocity of an at least one at least partially resonant actuator device;

controlling with the actuator controller computing device a driver system to output a driving signal based on the determined sequence of full bridge and half bridge outputs; and

providing with the driver system the driving signal to the at least one at least partially resonant actuator device.

8. The medium as set forth in claim 7 wherein the driver system is a full bridge driver device.

9. The medium as set forth in claim 8 wherein the full bridge driver device is configured to perform:

switching between a first and a second switching state for providing the full bridge output; and

replacing one of the first and the second state by a third switching state for providing the half bridge output based upon the determined sequence of full bridge and half bridge outputs.

10. The medium as set forth in claim 8 wherein the determining further comprises:

determining a duty cycle value for the full bridge driver device based upon a measurement of the output velocity;

incrementing an accumulator by adding the determined duty cycle value to a value of the accumulator;

outputting a half bridge cycle when the incremented value is less than a predetermined value of the accumulator; and

outputting a full bridge cycle when the incremented value is more than the predetermined value of the accumulator,

wherein successively outputting the half bridge cycle and outputting the full bridge cycle forms the determined sequence of full bridge and half bridge outputs.

11. The medium as set forth in claim 7 wherein the providing further comprises providing the half bridge output at an end of at least one of a low to high transition point of the full bridge output and at a high to low transition point of the full bridge output.

12. The medium as set forth in claim 7 wherein the instructions comprising machine executable code which when executed by the at least one processor, causes the processor to further perform controlling the output velocity of the at least one at least partially resonant actuator device in proportion to an amount of power consumed by the at least partially resonant actuator system,

wherein the amount of power consumed depends upon the determined sequence of full bridge and half bridge outputs.

13. An at least partially resonant actuator system comprising: an actuator controller computing device configured to determine a sequence of full bridge and half bridge outputs to substantially control an output velocity of an at least one at least partially resonant actuator device; and a driver system controlled by the actuator controller computing device configured to receive the determined sequence of full bridge and half bridge outputs and output a driving signal based on the determined sequence of full bridge and half bridge outputs, wherein the driver system provides the driving signal to the at least one at least partially resonant actuator device.

14. The at least partially resonant actuator system as set forth in claim 13 wherein the driver system is a full bridge driver device.
