1. An electronic positioning system for an actuator, comprising:
- an actuator operator configured to produce motion in an actuator in at least a first direction;
a sensor to ascertain the position of the actuator;
a controller that variably applies electrical power to said actuator operator to induce motion to be produced in said at least a first direction, wherein said variable application of electrical power is determined by motion sensed from at least one previous application of electrical power.

Abstract
Kinematic control of an electronic positioner and its associated actuator is effected through a control algorithm that delivers energy to the actuator based on observed motion produced by a previous delivery of energy. The algorithm achieves control based on a desired or user-specified resolution. Electronic braking between energy delivery intervals improves the speed at which the desired position is achieved. Temperature of the force producing mechanism is determined, as by monitoring energy consumed, and used to control how power is delivered to the actuator.

18. A method of controlling a motor comprising:
-
supplying a first quantity of energy to said motor to produce motion;
observing the motion produced thereby; and
supplying a second quantity of energy to said motor, wherein the second quantity is determined based on the motion observed.
