Abstract
A method for speed control for a motor of a locomotive of a model electric train is presented. A method in accordance with the present invention includes sensing an operating velocity of the motor and the operating current provided to the motor, and then producing a signal corresponding to the operating velocity and a signal corresponding to the operating current. A method in accordance with the present invention further includes providing the operating velocity signal and operating current signal to a controller and establishing a target motor velocity. A method in accordance with the present invention still further includes calculating a target current configured so that the motor reaches the target motor velocity, and then changing the operating current to the target motor current to achieve the target motor velocity.
