An approach for dynamic triangulation using servomotors

A novel principle of dynamic triangulation was developed at the institute of engineering UABC. This method of coordinate measurement uses stepping motors for laser positioning and an open loop controlled DC motor for signal detection. The present paper describes an approach for use of servomotors in cascade control loop, optimized with the amplitude optimum in the frequency domain. These approach results in a short rising time of the step response without overshoot. Simulations of the complete system approves the theoretically values.
