A high-speed position control system that achieves an accuracy of microns is described. The system, based on a printer mechanism, uses a linear encoder with 1000 lines per inch as the sensor and an interpolation scheme to achieve higher accuracy. The control algorithm uses the friction compensation algorithm developed by Friedland et. al. to eliminate hangoff and stick-slip. The system was tested in the laboratory and to have a 150 msec response time for a 1 inch step and an accuracy estimated as better than one micron.
