Multi-segment linearization of micro-actuator transfer functions

A method, comprising:

• setting a code value for a minimum displacement voltage point of an actuator response;
• setting a code value for a maximum displacement voltage point of the actuator response;
• setting a code value for at least one intermediate point between the minimum displacement voltage point and the maximum displacement voltage point, wherein the at least one intermediate point divide the actuator response into multiple segments;
• assigning a transform function with at least one respective coefficient for each segment;
• storing code values and transform function assignments;
• and
• operating the actuator in an open-loop control system using the stored code values by matching an input request to a segment of the actuator response and generating an output drive signal using the assigned transform function's respective coefficient for the matched segment.

A method comprising:

• receiving an input request to move a mechanical system;
• converting the input request into an input code;
• comparing the input code to segment endpoints of an actuator response, wherein each segment of the actuator response has an assigned transform function with at least one respective coefficient;
• based on the comparison, determining a segment in which the input code fits;
• applying the determined segment's assigned transform function using the transform's respective coefficient to the input code;
• and
• generating an output signal from the applied transform function code.
