1. An open-loop control system, comprising:

  • a plurality of code registers to store input code values for predetermined points of an actuator response, wherein the predetermined points divide the actuator response into multiple segments;

    a transform block to store transform functions with respective coefficients assigned to the multiple segments; and

    an accumulator, coupled to the code registers and the transform block, to generate an output control signal in the open-loop control system based on matching an input request to a segment of the actuator response and using the assigned transform function'"'"'s respective coefficient for the matched segment.
