1. A wearable infusion pump system, comprising:

  • a pump device including a drive system to dispense medicine from the pump device, the drive system defining an energy requirement profile to perform a medicine dispensing operation, wherein the energy requirement profile includes a gradual increase in the amount of energy delivered to the drive system during the medicine dispensing operation;

    a memory for storing the energy requirement profile of the drive system;

    an energy storage source to deliver electrical energy to the drive system; and

    a controller device configured to access the memory for retrieving the energy requirement profile and to initiate the medicine dispensing operation by supplying a pattern of voltage pulses from the energy storage source to the drive system, the pattern of voltage pulses being correlated to the energy requirement profile of the drive system.
