This paper considers the dependence of the performance of a Braille printer impact hammer on system parameters, specifically the lag time between subsequent current pulses and the location of a back stop constraining the oscillations of the hammer core. Here, the goal is to improve the printer speed while maintaining readability of the Braille type and preventing tears in the paper. Based on observations of the limit sets for the hammer-core dynamics, a low-cost feedback control algorithm is proposed for affecting the stability of otherwise unstable periodic oscillations with more desirable operating characteristics.
