title: A technique for eliciting muscular reflex responses using position controlled dc motors.
abstract: A method for generating fast ramp movements is described. A direct current (dc) motor serves as a drive in position feedback mode. In addition to a regulator and a power amplifier, basically only two relatively simple analog circuits are required. One is a ramp function generator with continuously adjustable parameters. The ramp function can be adjusted to the electromechanic transfer function of the motor. A second circuit comprises an analog position storage and allows the ramp to be started from any resting position.
